Tartaric acid is the white, powdery substance that coats tart candies such as Sour Patch Kids. Combustion analysis of a 12.01-g sample of tartaric acid-which contains only carbon, hydrogen, and oxygen-produces 14.08 g CO2 and 4.32 g H2O. Determine the empirical formula for tartaric acid.

Hello. So we started by uh getting the percentages of the elements. An example. Okay, so for the first sample, uh we're gonna find a percentage of carbon hydrogen oxygen. So to get the percentage of carbon or the percentage of anything is gonna be the so for example, kabul yeah, it's gonna be the molar mass of carbon. Yeah, divided by the molar mass of carbon outside. That's gonna be multiplied by the mass of carbon, divided by the mass of the sample. Okay, that's how we get the uh percentage of carbon. They're gonna do the same for the other element. So for hydrogen something Hamas divided by the molar mass of water and a mass of water divided by the mass of the sample. But of course, once you have a percentage of carbon and hydrogen, the total has 300%. Right? So you can easily find the percentage of oxygen by the addition of boat and take me from 100. Okay, so we got this. So now that we have the masses, we can establish the number of moles. Okay, so number of moles marks of our hula mouse. Okay, so you know the masses and of course the molar mass of oxygen is 16. So we get a match the number of moles. You do same for carbon and get this and then we'll get that for hydrogen. Okay, so now we have the masters for the masses and then the number of moles. Okay, judging the slide. So the second sample, we're gonna do the same thing. Okay, so have mullah Mansour s that suffer divided by the molar mass of S. 03 times massive ECE. Trade as a massive sample. Okay, so get this. Of course, once you do that behind a number of moles, you've got a test sample, you did the same thing for the nitric asset. Okay. And then the nitrogen, whether we get the uh percentage, which is also the mass, and then we have that. So once we get the look number of moles, we are almost set to get the empirical formula. Okay, So we just did the ratios of the number of moles. Okay. Which is does the oxygen, hydrogen oxygen, sulfur and nitrogen? Okay, so these are the values we got. Okay. And what we have to do here is to convert all of them into uh single vintages. Okay, We don't want fractures. Okay, so you're gonna divide by the smallest value? So the smallest value is what? 0.64. Okay, The smallest value. So if you divide all of them by 0.64, yeah, uh you're gonna get these ratios. Okay. That 5.96 point 94.91 and one. So you can around them to the nearest whole number and then get this. So this is gonna be our empirical formula. Okay, Thank you very much

Solution for stiff one. Then the word the mercies off CEO do and is trouble Do mercy's, uh, carbon end hydrogen respect Chua Li So we give for Dean point zero aid Go of Seo do into into one more offs. Your do divided by 44 point 0095 Good, um, offs You do, Indu one more off government divided by one more off CEO do in do well, point 01 07 Graham Good urban divided by one more off Gurban, is it? What do three point and Ford do? Six moore off carbon. So here, graham offs. Your do grammas. You're against wolves. You're Dumas loves you against a wall of carbon. Um, um all of Carmen Cancel. So here left is so I hear lefties drum off carbon and next he's 4.3. Do three. Do gram off a stool in. Do one more off his stool. Do allergic by it. Didn't find 0152 Grandma is to all into two more. Well, hydrogen divided by one more off a stool into one point. You know, zero sale on nine, but I'm off hydrogen. One more love hydrogen. Is it will do zero point for it. 33 and grandma hydrogen. So next he's solution for Step two. Use the combustion region. You know there to find the most off oxygen. So give speak. Pidgin must of oxygen is it Will do most of gum boned minus myself. Goodman minus myself. Hydrogen supporting male use myself. Oxygen is able to WellPoint. Do you know one? Get on my knees. Most of compound is three point it for so 6 g minus Must off carbon zero point for a 338 ground in most of hydrogen. Um, so the myself hydrogen, the zero point. Therefore a 338 g is equal to do seven point six it fours. You know, do grow more oxygen solution for stick tree gun work. Do morals off carbon, hydrogen and oxygen. So we have values. Three point it for to see scrum off Gurban into one more off urban divided by the world. Point 0107 And get on love. Goodman is it will do good. I'm off good carbon content with grandma. Carbon is equal to zero point 31993 more off Goodman. Then next he's ons it'll bind for aid. 338 Grandma, hydrogen in duel one more off Bedrosian, divided by 1.79 Grandma hydrogen is it will do. 0.47959 more love hydrogen grandma hydrogen Kinsale with each other in next ease. Seven point 6840 to mall off oxygen into one mole of oxygen, divided by 15 point 999 Four. More love oxygen is it will do zero point for a zero go salmon, More love accident, then step for solution for step for And then you're turning, do you know? But off moors off each element, the late Steve to deem other other element and then divide all quantities by the smallest amount of malls. Then multiply all coefficient. But I do in order to remove fractional politicians. So we have was little. 0.31 993 More love carbon divide By the smallest amount of Mali's 0.3199 tree, more is equal to one. Gurban Aidem. Next year's is your point for 7959 Moral of hydrogen. Divided very is your applying 31 993 more is equal to three y two more love by Georgian in next ease, you're going for a zero 27 more love oxygen. Do you read it? By 0.3 19 93 more is equal to three by two more of oxygen. So here, after removed the frictional coefficient So multiply all coefficients by to do into one carbon is equal to to a coven items and do into three by two High Georgian is equal to three hydrogen atoms and to Indu three by two oxygen is equally true. Three oxygen atoms so dear for that I am very good Formula is si Do it tree all three.

Solution for the able problem. Then, to find 52 grand, become bound bun produce for Boeing to it. Four point do a three good see or two and 1.1 g of its tool. First, let us find the most off carbon in more self Gurban in for going to tree grandma off. See you, too. So the Moller must ups you do. He's Moller Muss of Sio two is equal to 12th 0.2011 Bliss do burn 15 do in 2 15.999 is equal to 44.99 gone, but a moon the Merce but assumed off urban in CEO do is it will do 12.11 divided by 44.9 in 200% is equal to 27.29 person. Hence the most off German Gurban in 4.23 from Off Sio two is myself. Kurban in Sio. Two. Is it will do for going to tree Graham into going to see 1.29. Person is equal to 1.154 from, and the most person the most person. Uh, Goodman, you know Cuban come boned. He's most person of Kligerman. Is it? Well too 1.15 Food divided by 2.5 to ground into 100%. Messi will do 45.79 I listened. Stipp do no let find the most for Andy must off fide religion in 1.1 g off is too oh so deep Moeller myself it's tour Is Moller Mus off store? Is it well too? Do point do into 1.8 plus 15 find 999 is equal to 18.15 grand for more in the most person off H hydrogen in Ishwar He's must person, uh, hydrogen in h two is equal to do into 1.8 divided by 18 point is you know one file multiply 100% is equal to 11.19% hands the must off FIDE religion in one finds little One drama is stool is equal to 1.1 g into 11.19 person is equal to 0.113 grand and the must theme us percent off hydrogen in a given combined come bound. Is it going to 0.11? Tree graham Divided by 2.52 grand. I want to play. 100% is equal to 4.48% the wrong ground. Jensen instead tree for three. Here we have 4.1 for grandma off a come boned come boned, but I would use these Do 0.11 g off. It's a three lit. Let us find the most off flying the muss of sell for in 2.11 g off a so three. So the moller myself is the tree. This is a tree is equal to 32.66 plus three in do 15 0.99 is it will do 80.63 g per mole deep must but send oh sell for in case a tree is equal to 32.66 Divided by 80.63 multi play 100 is equal to 40.5%. Hints the most. The mars of sulfur in 2.11 g off eso tree is equal to 2.11 ground into 40.5% is equal to 0.8 for five grand and the must person must person off sell for inner de even come boned Come boned is it Will do 0.845 grand. You aided by 4.14 g. Went to play 100% is equal to 20.41%. Quote full five point 66 Gum Now If you come boned, produces 2.27 g of it in or tree, so let us find E must of most off night drudging in through 0.27 graham off it in a tree. So Moeller Mass Moller muss. Ah, get can A tree is equal to 1.8 plus 14.7 plus free into 15.999 is equal to 63 0.12 g per mole. More than myself, it's in a tree and the the mass percent off in must person off nitrogen in age in a tree. It in a tree. Music well too. 14.7 divided by 63 points you don't want to in 200 is equal to 22.2 in three person. Hence the months off hydrogen in. He must off my drawed in in through 0.27 graham off. It's in a tree. He's It will do 2.27 grand into 22.23. Person is equal to 0.505 g. It makes to behave the muss person off nitrogen in a given compound. Is it? Well too? 0.50 file, divided by 3.66 g multiply 100% is equal to 8.92 person, dear. For the most percent, uh, oxygen in given come burned is it? Well, too 100% minus 45 points A 29% minus 4.48% minus 20.41% minus 8.92 purse and is equal to 20.40 persons instead. Five. Let assumed it. We have 100. Grandma given compound even come Groaned. So so behave. We have 45 point save in nine graham off Goodman. 20.41 g off. Sell for 4.48 g off hydrogen, 8.9 to grandma off nitrogen in 20 0.40 g off oxygen. So Now we will find the number of more self eat compound we will find. Find the number off morels off each come boned, so each element. So number of Mall of carbon is equal to 45.79 divided by 12.11 is it will do three point aid, one more in number. Amman Off hydrogen is equal to four point for a divided by 1.8 is equal to 4.44 more. Next to behave. Number of full of sulfur but off more off silver is equal to 20.41 divided by so they do. Point 066 is it will do 0.636 small into a number of more off nitrogen is it will do. He had 0.92 Divided by 14.7 is equal to 0.637 moon you number one off oxygen is equal to 20.40 divided by 15.999 is equal to 1.275 mall. The elements with US moralist with the smallest amount of moans in a given component is is will be 0.6 36 moles. So we will divide the number of Morse off all elements with 0.636 and get the number it off. The number off carbon atoms is equal to 3.81 more do I did worry. 0.638 more is equal to six well, Morgenson and next to behave the number off Kurban, the number off number for hydrogen atoms, is equal to 4.44 more divided by the zero point 636 small approximately will do seven and the number of sell her Adams is equal to 0.636 more divided by 0.636 more is equal to approximately. We'll do one. I mean the number off. Night drudging. The eight domes is equal to 0.637 divided by little 0.636 Music will, too, approximately equal to when the number off oxygen atoms is equal to 1.275 more divided by 0.636 more approximately will do, too so dear for the I am very good for Mullah Coffee given compound he's even compound is C six. It's a one IHS in or do Oh, this is the empirical formula of human

Guys were doing Problem 100 Chapter three in chemistry. Malek approach guitar gas. It is the white powdery substance that coat start Candies. Such a sour patch, kid Combustion houses of 12 points year one gram sample of the tark acid, which ha jin and option produces 14.0 Graham CEO two and 4.32 grams Actual turned the empirical formula of to tar Cassidy. So this similar will be in question 98. We take the mass of our CIA to, for example, and we're gonna multiply it by the molecular weights the time ago carbon over the molecular weight of CIA, too. That's gonna give Give us the mass of our carbon 3.84 grams and then we get 4.32 grams of a shuo times, uh, times each be charging as a massive one. Grab Ramon and their two agents. So we have to have to over weight of water. It's gonna be 18 your 0.48 your point for a gram's and now to find the to find the weight of the oxygen is pretty simple. So we know the weight of our carbon, and we know the weight of our hydrogen. So the key to find the weight of our oxygen oxygen we just as we just do this good. The total weight minus the weight of our carbon minus the weight of our oxygen. Sorry. The weight of our hydrogen and that will give us the weight of the auction and are simple. Seven point 69 grams. Right now, we're gonna convert each of these two moles until we go at 3.84 grams. Then be one more for 12 grams, huh? 0.32 moles. Let me go four point 32 times. One more over one gram. So that so Sorry. Not 4.32 Oh, it's gonna be your 0.48 grams. Gonna be zero point for eight malls and then after June 6.6 nine nine grams, it's one more over 16 grams. Uh, okay. It's gonna equal. You're point for eight months. So next we're gonna divide everything by the least number of bowls. That means your point 832 over 0.32 is gonna equal one. And your point for eight. Where is your 0.3? Two is going to equal 1.5. So next we have todo. So as you can probably knows, we can't have an Adam. You can have half. And Adam, we have to have a whole Adam. So we have to convert this. Total numbers were gonna multiply everything by two. So one times two that's gonna equal to and then and it's gonna equal carbon. And then they go one 0.5 times two, which is gonna equal three hydrogen and oxygen. So that means that we can write the empirical formula for sample as C two h three 03
