Textbook Problem

Many transition metal salts are hydrates: they contain a fixed number of water molecules bound per formula unit of the salt. For example, copped(II) sulfate most commonly exists as the pentahydrate, ${\text{CuSO}}_{\text{4}}.{\text{ 5H}}_{\text{2}}\text{O}.\text{ If 5}.00{\text{ g of CuSO}}_{\text{4}}$. ${\text{5H}}_{\text{2}}\text{O}$is heated strongly so as to drive off all of the waters of hydration as water vapor, what volume will this water vapor occupy at $\text{35}0.°\text{C}$and a pressure of $\text{1}.0\text{4}$atm?
