Mass of copper in copper sulphate:
Given: weightofCuSO4=100 g
MolarmassofCuSO4=1×63.5+32×1+16×4=159.5g mol−1
From the formula of CuSO4, it is clear that 1 mol of CuSO4 contains 1 mole of Cu. or 159.5 g of CuSO4 contains 63.5 g of Cu
Mass of Cu in 1gof CuSO4=63.5159.5gofCu
∴Mass of Cu in 100gofCuSO4=63.5159.5×100 gofCu
Hence, amount of Cu=63.5×100159.5=39.81 g
Final answer: Amount of Cu in 100 g CuSO4 is 39.81 g
