3. Another way to calculate the number of waters hydrated to an ionic compound is through it's precent composition. An unknown aluminum sulfate hydrate has the formula Al2(SO4)3 ZH2O. If the entire compound is 8.10% Al by mass, calculate the Z value, or how many water molecules are associated with the aluminum sulfate.

Expert Solution
Step 1
Molecular weight of Al2(SO4)3.ZH2O = 27x2 + (32+16x4)x3 +Z x (2x1+16)
= 54 + (96x3) + Zx18 = 342+18Z
Now mass % of Al = 8.1 (given)
Or,
(54 / (342+18Z)) X 100 = 8.1
So,
Z= 18
