A student started with 1.622 grams of copper (II) oxide and produced 3.500 g of copper (II) sulfate. What is the percent yield? The product is a hydrate. Use appropriate significant figures. Do not put a percent sign in the answer box.

Useful information: chemical equation: CuO(s) + H2SO4 (aq) ---> CuSO4 (aq) +H2O(l)

Formula weight of hydrated copper (II) sulfate = 249.6 g/mol
