Calculate the mass in grams of each of the following samples. a. $6.14 \times 10^{-4}$ moles of sulfur trioxide b. $3.11 \times 10^{5}$ moles of lead(IV) oxide c. 0.495 mole of chloroform, $\mathrm{CHCl}_{3}$ d. $2.45 \times 10^{-8}$ moles of trichloroethane, $\mathrm{C}_{2} \mathrm{H}_{3} \mathrm{Cl}_{3}$ e. 0.167 mole of lithium hydroxide f. 5.26 moles of copper(I) chloride

When we're converting between given quantities of measurement describing amounts of substances it's helpful to draw out a roadmap were planned to know which conversion to use when. So if, for example, we're starting off with a given quantity of Yuri's in this case 8.35 moules of copper, one carbonate. Okay, and we want to know the mass equivalent or how many grams to go between moles and mass. The relationship that we use is the molar mass, and we find the molar mass by using the formula of the compound and the periodic table. So to figure out what copper carbonate is copper is See you in the room. Number one indicates it's got a charge plus one. The carbonate ion is CEO three tu minus. So to make it a neutral ionic compound, the formula is see you too, CEO three. And then using our periodic table, we find the molar. Mass. One mole is equal to the mass of copper from the periodic table times two so two times 63 0.5 46 plus the massive carbon 12.11 plus three times the mass of oxygen. So these numbers here have all come from the periodic table is the atomic mass of each element. And so when we multiply and add them together, one mole of copper Kirk Copper carbonate has a molar mass of 187 0.10 grams. So using this relationship, the molar mass. If we have 8.35 moles, we can change it to grams by multiplying by the molar mass. So we multiply 8.35 times 187.10 or a molar mass of a total mass of 1.56 times 10 to the third grams. So 8.35 moles is equal to 1.56 times 10 to the third cramps. Another example. We might be given molecules instead of molds when we have molecules. The relationship that we used to change two moles is Allah God rose number because that tells us that in every mole there are 6.2 times 10 to the 23rd molecules. And then if we want to go from molecules two grams after we changed two moles, we again use our molar mass. So in this case, We're talking about a compound called Die Nitrogen hence oxide. So to find the molar mass of die nitrogen pent oxide, we find the formula. We know that it has nitrogen and the dye means there are two. It has oxygen and the pent means five. So I have n 205 So we confined our Moeller Mass just like we did above by multiplying two times the molar mass of nitrogen were 14 point 007 plus five times the molar mass of oxygen 15.999 We're one more is equivalent to 108 0.1 grams. This is a two step problem where we first start off with our molecules. We changed two moles using of a god rose number one more is equal to 6.2 times 10 to the 23rd molecules. And then we changed two grams using our Mueller Mass. We're one more has a mass of 108.1 grams, so multiplying 4.4 times 10 to the 20 times 108.1 women dividing by 6.2 times 10 to the 23rd gives us the answer of 0.0 7 to 5 grams. You may be given a mass to start with and then find quantities and moles, formula units and then even smaller descriptions based on what the chemical formula is. So if we have 78.9 grams of a compound called sodium per chlorate, we can find how many moles this is equivalent to and again grams to moles. We use the molar mass. We confined on a smaller level. How Maney formula units this is equivalent to, and a formula unit is just the smallest unit of an Ionic compound. So again, we use Allah God Rose number. So before we start converting, we need to figure out what sodium per chlorate is. Sodium is an eye on an A plus. The per chlorate ion is C L 04 with an overall minus one charge. So the formula is N a. C l 04 and the molar mass is equal to the mass of sodium plus the massive chlorine plus four oxygen's or 122.44 grams so I can convert from my given grams, two moles because I want it in moles I divide by the Moeller math. So 78.9 divided by 100 and 22.44 in this equals 0.644 moles find the equivalent and formula units. I take my number of moles and I multiply by Abu God Rose number So this equals 3.88 times 10 to the 23rd formula units Ah, an a c l o For we can use that information to break it down even further If I want to know how maney sodium ions there are for every formula unit of an a c l 04 there is one sodium ion. So if I have 3.88 times 10 to the 23rd formula unit, I will also have the same amount of sodium ion. Similarly, for every formula unit, I have one per chlorate ion. So I should also have 3.88 times 10 to the 23rd quarry. I am for every same quantity of formula units. If I want to know how many chlorine atoms, if I look at the formula here in this formula for every one of these, there's one chlorine Adam. So if I have 3.88 times 10 to the 23rd formula units, I should have the same amount of chlorine atoms or 3.88 times 10 to the 23rd Chlorine atoms. If, however, I ask how maney oxygen atoms are, you can see that in one formula unit there are four oxygen atoms. So that means that there will be four times as many oxygen atoms in the given quantity. Okay, who are 1.55 times 10 to the 24 atoms of oxygen.

So the molar mass of a substance is the massing grounds of one mole of the substance. And here we're taking a look at compounds where a compound is a substance that contains atoms of two or more different elements in these atoms are chemically joined together so fastly what we have is boron try fluoride. We're starting off with Iron three oxide and part a. Which has them all a massive 159.688 g per mole. Next we have the boron try fluoride, Which has the mass 67.806g per month, followed by dying nitrogen oxide, Which has the Molar mass 44.0128 g per mole. And so next what we have is manganese to chloride, Which equals 197 .905 grams per mole. And finally what we have is ascorbic acids. We've got vitamin C, Which is 176 .1238 g per mole.

Solution for But in step one, one word must cease to Moore's using Muller muss Mercy's next inward waas into Milly Moore's, then determine didn't but, Ah, Moors Oh, each the lee means the Lady Eve to the other. Elements divide oh, quantities by the smallest in bombed of merely moms. Look, so we hear believes 1.6 by fun of a G into when more love e G.

Milly Moore's Oh silver, divided by one more off syllable, is equal to 15 wind free 057 Merely moles off, similar in Next to be if if you don't mind one due to for Gramma oxygen into one more off oxygen divide by 15 point 9994 Grandma Oxygen into goes and milling roll of oxygen divided by one more. Off exceeding. Is it well too, seven point six 503 Really wall of oxygen. So here graham off oxygen concern from all of boxes in Kinsale so left it is minimal of oxygen, and we hear 15.3057 Milly, mole of silver divided by 7.6501 Really more is it will do more love. Ciller's and 7.65 Little three, divided by three million more off oxygen, divided by 7.6501 Really more off many more. Is it going to one oxygen? One more off oxygen so dear, for so there for the and Danny for Mullah is G. Do Oh, in step, do but be solution. Convert these mercy's do malls using Moller Mercy's NextGen word moles into Millie Mel's, Then Did you mind? Did Mindy number of walls of each really meant related to the what that really means. Divide all quantities by smallest in murder, merely morgues eliminated Fractional frictional coefficient by Monty playing all coefficient by two. So you used little 0.67 Do Graham off carbon monoxide into one more off Herman Mono site. Divide by 58.9. Tree tree to grandma of carbon monoxide into Goes in Milly. Moral off carbon monoxide divided by one more love. When one upside is equal to 11 point who, as you know three. Milly Moral of Goodman. One. Off site cancer can sell Malkin Silken cell in next ease 0.569 that I'm love student into one more. One more This stadium divided by 74.9216 Good. Um, a stadium into goes in merely mold. Stadion divided. Buying one more. The state in easy to 7.5946 Muli Mold office stating So here, Graham can send role model consent to live with this minimal and next to give was your brain for a six grandma succeeding into one more off excision Diverted way. 15.999 For gamma succeeding into those in merely more off oxidant divided by one more love exceeding is equal to three point 376 merely more well exceeding. So here, Gram Gram concealed more more concerned left this Milly mode well, oxygen in next. It is 15.30 while you save one, many more see or do eroded by the smallest Iman tamales. Seven. William 65 gentle one Milly Mall is equal to three by two. Could've been monoxide in seven point 7.6503 really more. It's did in divided way, say, 1.65 little one many more is equal to when more love stating and the next one is 30 Blind 376 Milly, Mall of Oxygen Divided way Sumer list Amount. Um, only 7.650 When mini mall is it will do for more love accident. So here we hear two into tree by do see or is it going to increase the old and here two in new ones is sticking is able to do stating And here we have to indu for oxygen was able to add oxygen deal for sh The in very good formula Mullah is see or tree it is too or it stick tree in solution for barred seem solution Cardboard sea could be here Convert the masses to malls using molar masses. The next one word malls into Millie malls Then determine the number of malls off it. Element related to other elements. Divide all quantities by the smallest amount of millennials. So the solution off this is when one point for for tree gone S e into one more is e divided by 78 point 96 Good. Um, s e into those on merely well of is a divided by one rule of E. Is it going to a Dane? Billions getting going through seven. Five Mill Imola is e so your gram gram can seem more can said so. Let these Millie Mullah, Is he in? Next? He's five point 841 Be, uh, into one more b r divided by, say, 19 0.904 Grown be, uh into does in merely mole. Be, uh, do you already buy one? We'll be a is equal. Do 73 point 100 really more be a me and 18.275 Merely more is e diverted away. It didn't point through 75. Milly more is equal. Group one more is E and and seal into a tree. 0.100 Milly more Be good. Do I did way 18 point through 75 Milly moon is it will do for be a So the in medical formula is mullah Is is e be, uh, for

I even saw in this question. They are calculated Mosque in grams of the following E. 1.25 more calcium prospect yeah. 1.25 more calcium or spade. No we know that w that is waiting grams That is equal to an into em. So 1.2 for you are the camera phones into moller muscle calcium phosphate is 310.18. And therefore therefore mosque in grams. Moss in ground that is equal to 387 point 71 for you. Uh huh. Mhm grabs then the second one. Yeah. 0.600 micro moll op. C. For age 10. Micro more. Love see forage 10 C. For 8 10. So this is equal to yeah 0.600 in to challenge to minus six. So we know that w it is recalled to any into em and that is equal to point 600 in. To tenders to minus six into 15.12. And therefore moss Ingraham. Yeah that is equal to 3.49 into appendage to minus five g. Yeah then see fart. Yeah. Yeah 0.62 for you. Millie mola ram. Really Mall F. E. And that is equal to I am 62 for you in to tenders to minus three mola firing. So I believe he can to end into end and that is equal to 0.625 into english to minus three into 41.86. And therefore mass in grams notice equal took. Sure. Yeah. Find 15 11 6 to 5 grand. Then be part one point 45 malt ammonium carbonate fact. So and I believe he can do any into young and that is equal to 1 45 into moller nasa ammonium carbonate 96.9 And therefore Massing graham of ammonium carbonate. That is equal to 1 39.33 Yeah 29 23 grand. Think
