Calculate the percentage of water of crystallization in hydrated copper sulphate [CuSO 4 .5H 2 O]. [Cu = 63.5, S = 32, O = 16, H = 1]

Molecular weight of hydrated copper sulphate CuSO 4 .5H 2 O = 63.5 + 32 + 4(16) + 5[2(1) + 16] = 63.5 + 32 + 64 + 5[18] = 63.5 + 32 + 64 + 90 = 249.5 g 249.5 g of CuSO 4 .5H 2 O contains 90 g of water of crystallization. Percentage of water of crystallization = x 100 = 36% Hence, percentage of water of crystallization is 36%

State which of the following are better fertilizers —
(i) Potassium phosphate [K₃PO₄] or potassium nitrate [KNO₃]
(ii) Urea [NH₂CONH₂] or ammonium phosphate [(NH₄)₃PO₄]
[K = 39, P = 31, O = 16, N = 14, H = 1]
