Chapter 14, Problem 107IAE

A saturated solution prepared at $70°\text{C}$ contains $32.0\text{g}$ ${\text{CuSO}}_{\text{4}}$ per 100.0 per solution. A 335 g sample of this solution at $\text{0}°\text{C}$ is ${\text{CuSO}}_{\text{4}}\text{/100g}$ soln, what mass of ${\text{CuSO}}_4\cdot 5{\text{H}}_{\text{2}}\text{O}$ would be obtained? [Hint: Note that the solution composition is stated in terms of ${\text{CuSO}}_{\text{4}}$ and that the solid that crystallizes is the hydrate ${\text{CuSO}}_{\text{4}}\cdot 5{\text{H}}_{\text{2}}\text{O}$ would be obtained? [Hint: Note that the solution composition is stated in terms of ${\text{CuSO}}_{\text{4}}$ and that the solid crystallizes is the hydrate ${\text{CuSO}}_{\text{4}}\cdot 5$ .
