How long will a current of 1 ampere take for complete deposition of copper from 1 litre of `1NCuSO_(4).5H_(2)O` solution ?

What is the current efficiency of an electro-deposition of copper is deposited of copper metal from CuSO_(4) solution in which 9.80 g copper is deposited by the passage of 5 ampere current for 2 hour?

How long will it taje 5 ampere of current to deposit 2 g of copper from a solution of copper sulphate ? (Given : CE of copper =32, F=96500 coulomb)

A solution of CuSO_(4) is electroysed for 10 minutes with a current of 1.5 amperes. What is the mass of copper deposited at the cathode ? (Molar mass of Cu=63.5 g//mol)
