Chapter 3, Problem 72E

Anhydrous sodium sulfate, ${\text{Na}}_{\text{2}}{\text{SO}}_{\text{4}}$ absorbs water vapor and is converted to the decahydrate, ${\text{Na}}_{\text{2}}{\text{SO}}_{\text{4}}\cdot {\text{10 H}}_{\text{2}}\text{O}\text{.}$ How much would the mass of 36.15 g of anhydrous ${\text{Na}}_{\text{2}}{\text{SO}}_{\text{4}}$ increase if converted completely to thedecahydrate?
