When copper(II) sulfate pentahydrate is heated in air above 100C, it loses the water molecules and also its blue color. CuSO4•5H2O—>CuSO4 + 5H2O If 9.75 g of CuSO4 are left after heating 15.25 g of the blue hydrate, calculate the number of moles of water originally present in 15.25 g of the hydrate.

When copper(II) sulfate (CuSO4) is prepared from copper(II) nitrate and sodium sulfate, the reaction initially produces a hydrated product, copper(II) sulfate pentahydrate (CuSO4.5H2O). If the CuSO4.5H2O is heated, the water is removed, leaving anhydrous CuSO4. What mass (in grams ) of anhydrous CuSO4 will be produced from 2.05 g of CuSO4.5H2O?
