Find the percentage of water of crystallisation in CuSO 4 .5H 2 O. (At. Mass Cu = 64, H = 1, O = 16, S = 32)

Relative molecular mass of CuSO 4 .5H 2 O = 64 + 32 + (4×16) + [5(2+16)] = 96 + 64 + 90 = 250 250 g of CuSO 4 .5H 2 O contains 90 g of water of crystallisation ∴ 100 g of CuSO 4 .5H 2 O contains = x 100 = 36%
