A current of 2 ampere was passed through solutions of `CuSO_4` and `AgNO_3` in series. 0.635 g of copper was deposited. Then the weight of silver deposited will be-

A current of 2 ampere was passed through solution of CuSO_4 and AgNO_3 in series. 0.635 g of copper was deposited .Then the weight of silver deposited will be:

A current of 0.2ampere is passes through a solution of CuSO_4 for 10 minutes calculate the man of Cu deposited on the cathode.

A current of 2A was passed for 1.5 hours through a solution of CuSO_(4) when 1.6g of copper was deposited. Calculate percentage current efficiency.

A current of 2A was passed for 1.5 hours through a solution of CuSO_(4) when 1.6g of copper was deposited. Calculate percentage current efficiency.

The chemical equivalent of copper and zinc are 32 and 108 respectively. When copper and silver voltameter are connected in series and electric current is passed through for sometimes, 1.6 g of copper is deposited. Then, the mass of silver deposited will be
