Consider a zinc electrode in a concentration cell that is connected to a copper electrode through a salt bridge. During the electrolysis of an aqueous solution of ZnSO4, a current of 2.5 A is passed through the cell for 20 minutes. Calculate the mass of zinc deposited on the electrode during this time assuming 100% efficiency. (Molar mass of zinc = 65.38 g/mol)
