Question

How much copper can be obtained from 100 g of copper sulphate(CuSO4)? (Atomic mass of Cu =63.5amu) 

Solution

Correct option is

39.81 g

 

1 mol of CuSO4 contains 1 mol (1 g atom) of Cu

Molar mass CuSO4 = 63.5 + 32 + 4 × 16 = 159.5 g mol–1

Thus Cu that can be obtained from 159.5 g of CuSO4 = 63.5 g

∴ Cu that can be obtained from 100 g
