    How much copper can be obtained from 100 g of copper sulphate (CuSO4)?
    Ans : 1 mole of CuSO4 contains 1 mole of copper.

    Molar mass of CuSO4 = (63.5) + (32.00) + 4(16.00)

    = 63.5 + 32.00 + 64.00

    = 159.5 g

    159.5 g of CuSO4 contains 63.5 g of copper.

    ⇒ 100 g of CuSO4 will contain of copper.

    ∴ Amount of copper that can be obtained from 100 g CuSO4

    = 39.81 g
