Answers

Aspirin can be made in the laboratory by reacting acetic anhydride $\left(\mathrm{C}_{4} \mathrm{H}_{6} \mathrm{O}_{3}\right)$ with salicylic acid $\left(\mathrm{C}_{7} \mathrm{H}_{6} \mathrm{O}_{3}\right)$ to form aspirin $\left(\mathrm{C}_{9} \mathrm{H}_{8} \mathrm{O}_{4}\right)$ and acetic acid $\left(\mathrm{C}_{2} \mathrm{H}_{4} \mathrm{O}_{2}\right) .$ The balanced equation is:
$$\mathrm{C}_{4} \mathrm{H}_{6} \mathrm{O}_{3}+\mathrm{C}_{7} \mathrm{H}_{6} \mathrm{O}_{3} \longrightarrow \mathrm{C}_{9} \mathrm{H}_{8} \mathrm{O}_{4}+\mathrm{C}_{2} \mathrm{H}_{4} \mathrm{O}_{2}$$
In a laboratory synthesis, a student begins with 3.00 $\mathrm{mL}$ of acetic anhydride (density $=1.08 \mathrm{g} / \mathrm{mL} )$ and 1.25 $\mathrm{g}$ of salicylic acid.Once the reaction is complete, the student collects 1.22 $\mathrm{g}$ of aspirin. Determine the limiting reactant, theoretical yield of aspirin, and percent yield for the reaction.

Question. Number 91 has been asking integration by the equation. C 48643 on the C seven at 600 You mean see united for over Lyon? It's eight or four. Let's see to H four or two. This is acidic and Heidrick, See as you walk on. This is salicylic acid. Certainly, Silicon said on the product is has pretty. This is a technicality. In this synthesis, I said, You can hide red with a density of 1.8 John Parimal five million off a silicon hydrating, an entity 1.0 age and 2.8 grandma salicylic acid. He's taken 2.0 media. On completion of the reaction, the amount off spring isolated is 2.1 g, 2.1 g. A student was isolated. So this is actually here This Now we have to determine the limiting reactant theoretical yield on the person is use of the reaction. First, let us see which is a limiting, reacting to see that you mean trying to find out the and Mondo I think and hatred anyway for the conversion off. Why Gramps? Higher melt off a sitting and hydrate. That is when that we will first find out, do you more almost immediately reacted Pacific and hightail. 102.1 salicylic acid 1. 38.1 and have spending money 2.1 23.2. So that is we have the morning losses. No, the months of Pacific and Hillary's five into Why you in Duke? 1.8 Yes, No. 102.1 g needs 1 38.1 Grandma Salicylic acid. So one grandma, Pacific and heart. It needs one ground. Is he doing news? 1 38 or any money before one or two points? 1 g Most Alice legacy. So five into or not 1.8 Graham needs into files in the 1.8 This is the theoretical requirement off this acidic inheritor. Now that will work out to be seven point three times 7.3 g. Sorceress, You guys, this is a complete consumption, but we have only 2.8 g of salicylic acid. That means salicylic acid is a limiting Create. This is the limiting rate. Once you have found the limiting creative We will find out how much off aspirin will be formed. The trump the limiting created for dead our basis of calculation is 1 38.1 Graham, seriously, Gossip producers 1 80 point to grandma as we so 1 g will produce 1 80 going to a born 1 38.1 graham as police and hence 2.0 8 g, 2.8 g. Absolutely like acid. We can create this multiplied by you want to read? This works on to me 2.71 g off. Thanks for you. So this is the theoretical lead the product found is 2.1 g actual properties. Actually, these 2.1 club which is between indeed the skin itself So the person is killed equals 2101 in 200 upon 2.71 that equals 74.1%

Let's determine that the meeting reacting theoretical. You'll of aspirin and percent yield starting from three milliliters of acetic anhydride to see for each six go three and 1.25 grams of the, uh, salicylic acid si seven age, 603 We're first going to find the limiting reactant by converting both of these two moles of aspirin. So, uh, first will play the density here. 1.8 grams, see for 603 per militar, see for each 603 molar mass 102.9 grams of C four h, 603 for one more and start geometry. One more see for each 603 to 1 more of aspirin, which is C nine h 804 and this would give us 0.317 moles of the C nine h h 04 Now let's do this for the salicylic acid. Uh Moeller Masters 138.12 grams c. Seven h, 603 one more story geometry. One more si 78603 to one more of the C nine h 84 and this works out to 0.905 moles of the C nine h 84 this one and see Lester amount. Therefore, the limiting reactant based on the lesser amount of aspirin produced is the sale of Cilic acid H seven Cease H 603 Now let's find the um, theoretical yield of the, um aspirin C nine h eight or four, starting from 40.905 Moles c nine h 84 One more has a mass of 180 What. One grams? And this works out to theoretical yield of 1.63 grams of C nine h eight 04 So there's a theoretical yield, and then the percent yield would be the actual amount given in the question. The 1.22 grams divided by the 1.36 grams is a theoretical yield and sold them for a percent yield. We find that it's equal to 74.8%

Given information is see salmon in six or tree less. See for it seeks or three interests. See nine. It's it. 04 less see do each for or do solution for part A. The most off s buring. It's bring C nine. It's it. 04 He's myself dispiriting IHS billing Isaac. But do zero point for digital ground and we have to find the myself. Still, I say frolic as it see Suman in six or three. I need it to produce a given amount of spring first and we believe for in the number off moons off spring. The Moeller Moss itself is a marine. He's moral myself is Brene. Music will, too. Nine. Indu Mowlam us off carbon less it into more than myself Hydrogen bliss for into more than myself, oxygen is equal to nine into small amounts of carbon. Ease the 0.11 around Baltimore, plus it into Muller myself. Hydrogen ease one 0.8 to drown Baltimore less for into Muller must off oxygen east 15.99 The Berman is able to the kill collected merely wealth. Muller myself s preemies one 80.159 drum Permal. That number of Morse off spring is is greenies. Number off Moore's Off IHS Spring is equal to given months off spring Divided by more than myself, this dream is equal to given myself Esprit Mies three Point Falls Original ground divided by the molar masses 1 80 brained 159 ground But more is it will do 20 to a point changing do into 10 raised to the power minus three more. And here, one more love I sprained his produce by one more love. Sly secular. Guess it hence. 2.2 into 10 Raised to the power minus three months off. Esperan will be produced by DOH Point Drew Drew into 10 Raise to REpower, minus three more laughs. A cell recycling is it? Now we can find the myself silly psychedelic as it. So the mother myself solely psychically Isett. He's Moller myself silly. Say kill Weak IHS Seat is equal to seven into Moller myself. Carbon plus six into Moeller myself Hydrogen plus trey into Mordor myself. Occident is equal to seven into Mullen must've carbon Mistral 70.11 ground Permal plus six into Muller muscle for drugs in his 1.8 grand Permal plus three into modern months off oxygen is 15.999 down on the moon. So they calculated Moller myself, Selous a colleague, as it is equal to 1 38 point. We went toe to good on Thermal and the myself Sally, say Colleague s it its seat myself Silly psychedelic is it is equal to number of Moore's off Sally. Say Kelly, guess it into Mordor myself. Cell is a colleague is it is it will do Number of more subsidy Circulate s cities two in doof toe point due to into 10 raised to the polar Ministry malls into one Terry it point. I went to two grand for wool. Mr. Moreland myself said, It's actually gets it the calculated myself Silly cycle. I guess it is zero point trees, you know, salmon. But, um, in given information for part B si seven if 603 bless, see for it Seeks or tree into C nine. It's it Go for less C two h four or two from part A bean. We know that we need we need 0.3 07 But I'm, uh, silly say Gaelic is it? Now we will find the Imam Duff silly psychically as you needed. If keep on Lee 74 0.9%. Oh, Sally saying Kelly issued these can virgin too, converted to a spear in. So if 0.307 good arms is 74.9% distorting this starting 100% would it be would be myself Silly cycle lead Acid music will do 0.307 grand divided by 74 point 9% into 100% is equal to zero point 410 grand. The completed myself sadly say killing is it so the starting myself Silly Sokolich s. It should be zero point for 10 ground given information for Farsi si seven it six or tree plus. See for it Seeks or three c nine It it 04 plus c do each four or do the most off slowly psychedelic is it is myself. Silly psychedelic Isett is equal to 9.26 Wrong. I mean the most off it's Santic in hind, right? He's myself is a chicken hydrate. Physical too. 8.5 foreground. In the actual Hield Love s spring he's then point nine go. We have to find that he already go wheeled off a spring in the percent yield. First, we will find the limiting reactant. And so the psych, the cell recycling Isett Mullah Omar's he's from But A is 1 80.15 nine that, um, but I'm one the esprit in Molar, Mass. As billing more than Tomas is from. But he he's 1 80 0.1 fire, nine ground bottom, all in tears. OD d myself. Certainly Seguela Guess it the Muller myself selling cycle. I guess it is from Bart is 138 1 38 0.1 to 2 g per mole. The aesthetic in Hyde right molar Mass is more than myself in high, right in hind, right? Ascetic music will do for into Moller myself. Carbon bless six into more than myself, hydrogen less shea into modern myself. Oxygen is equal to four into monogamous of carbon ease, 2.11 ground barmal plus six into Muller. Myself, hydrogen is 1.8 ground Barmal less. Three. Intramural almost oxygen is 15.999 ground, but more is equal to the calculated Moeller myself is a tick in hydrate is 10 through 100.0. It's nine ground, but more the number. Morel's off the Celis Savior Leak. Yes, it is number more love. Silly Cycle week Isett is it 12 given myself silly family s it divided by more than myself, Sandy say Kelly. Yes, it is it 12 given must seize nine point tour six. Bram divided by the molar masses 1 38 point when to go to ground for moon is equal to see explained seven Digital into 10 Raised to the power money store More in the number of more self citic ane hydrate is in Citic in high dried peas number more self This attic in I write is equal to must And Sadiq in Hyde, right? Divided by more than myself Ascetic in I'd write is equal to myself acidic and hydride Is it joined by Forge How divided by Moeller myself A citic in hydrate is 102 point 089 Damn, but moon is equal to it. Going 37 into Kendra's to recover minus toe More is the calculated more stuff. It's a dip in hydrate and since one mole off Sally Seguela. Guess it really exit with one mole off ascetic in Hyde, right? 6.70 into 10. Raised to the Power Ministro mall offset cycle it is. It will react with 6.70 into 10 raised to the power minus two. Mullah aesthetic in hydrate dear for the limiting, Regency's sadly say Kelly. Yes, it So here, Dear for daily meeting, Maria Dandy's solely sigh Callie Acid and one more laugh. So this is like a like a seat produces one mole off a spring hands, 6.70 in tow. 10 Rest of the power minus two more self silly secular guess it will produce 6.70 into 10 raised to the power minus two moles of a spring. Now we can find that you were to go yield off spring and so that your It eagle wield is it will do six point 70 into Kendra's to devour minus stool more into 1 80.159 that I'm. But a more is equal to to WellPoint 07 go. Therefore, in the person yield is the percent yield is equal to that actual, he yield divided by, uh two Ready? Go. The old into 100 person is it will do the actual your is 10.9% divided by the terror tickle guilties to well 0.7 The actual guiltiest 10.9 drum in the political religious school 0.7 grand in 200% is it will do 90 Going three person is the person killed. So the result is that you critical yield off is three knees. Spring is we're 0.7 g and look purse end yield off s spring is 90 pine tree percent the 60 by now result
