An electric current is passed through a solution of (i) silver nitrate, (ii) solution of 10 g of copper sulphate (CuSO_(4).5H_(2)O) crystals in 500 mL of water, platinum electrodes being used in each case. After 30 minutes it was found that 1.307 g of silver has been deposited. What was the concentration of copper, expressed as grams of copper per litre in the copper sulphate after electrolysis ?
