To determine the charge on the ion of metal X, a current of 1.0 A was passed for 16 minutes 5 seconds through the molten chloride of metal X. 0.32 g of metal X was deposited at the cathode. The relative atomic mass of metal X is 64. (1 F = 96 500 C)

1. aCalculate the quantity of electricity in coulombs passed through the molten chloride of metal X to produce 0.32 g of X. [2]
2. bCalculate the quantity of electricity which will produce 1 mol of metal X. [2]
3. cCalculate the number of faradays which are needed to produce 1 mole of metal X. [2]
4. dWhat is the charge of the ion of metal X? [1]
