Problem 10 Easy Difficulty

Calculate the molar mass of each of the following:
$$\begin{array}{llll}{\text { (a) } \mathrm{SnO}} & {\text { (b) } \mathrm{BaF}_{2}} & {\text { (c) } \mathrm{Al}_{2}\left(\mathrm{SO}_{4}\right)_{3}} & {\text { (d) } \mathrm{MnCl}_{2}}\end{array}$$


a) $\operatorname{Mr}(\mathrm{SnO})=134,71 \mathrm{g} / \mathrm{mol}$
b) $\operatorname{Mr}\left(\mathrm{BaF}_{2}\right)=175,33 \mathrm{g} / \mathrm{mol}$
c) $\operatorname{Mr}\left(\mathrm{Al}_{2}\left(\mathrm{SO}_{4}\right)_{3}\right)=342,19 \mathrm{g} / \mathrm{mol}$
d) $\operatorname{Mr}\left(\mathrm{MnCl}_{2}\right)=125,81 \mathrm{g} / \mathrm{mol}$

we have to kill the mother mass off four different compounds. The 1st 1 will be SN. Ow! So, um so we just did. You filed more than Mass off ascend. And then we found them all Massa for when their mouths are numbered. But we'll get them together. So yes. So we were referred to you appear on the table. So it would be cost one into our aprons, saving for sn and also only be 16. So we're headed together. You He calls to one for a 4.7. Quinn promote the second librarian for Why so forbearing? We won 37.2 plus two for I two time 19 where 175.2 Forever himself a jar. It'll be no other. The complicated. But that year is pretty easy. So for album and we knew that is 26.98 for each element. So we had 26.98 times two. Plus we have free unit off self ate. So for Sophie, we have one suffer for oxygen. So we just let you go for self. Various 28 for 09 plus 16 Signed. Four So 24 or night time about plus 16 size for now that we you know, we started here. All right, so Ah, for suffering for 28.9. And then we have oxygen will be 16 times for And then we just need Thio used to a collector and, um, at all number together. And then we should be able to find that the more the masses for your 4 to 4 in 17 grand for Mo and for ah, Magnus core. Right. Maybe this to correct where 1 24.94 gram promote because we're one. Um, Maggie is this free 4.944 GOP order table. Plus, we have to foreign few 35 each, and then when you add them together, we should be able to file that the system over mass off.
