Calculate the percentage of water of crystallization in CuSO 4 .5H 2 O (H = 1, O = 16, S = 32, Cu = 64)

Answer Molecular mass of CuSO 4 .5H 2 O = 64+32+64+5(18) = 250 % of water of crystallization = 5×18/250 × 100 = 36%

Calculate the percentage of water of crystallization

Calculate the percentage of water of crystallization in CuSO₄.5H₂O (H = 1, O = 16, S = 32, Cu = 64)

Molecular mass of CuSO₄.5H₂O = 64+32+64+5(18) = 250

% of water of crystallization = 5×18/250 × 100 = 36%
