Question

Suppose you need to produce 25.0 g of pure copper by electrolysis of a solution of CuSO, (aq), by the reduction, Cu2+ (aq) + 2 e- + Cu(s). How much time will it take with a current of 3.00 A? Coulombs Amps x seconds. Faraday's constant is 9.65 x 104 C/(mol e-) and the molecular weight of Cu is 63.5 g/mol
