The no. Of gram equivalent of copper deposited on the cathode will be 5 g equivalent.

Explanation:

1 electron carry charge=1.6\times 10^{-19}C

1 mole of electrons contain= electrons

Thus  1 mole of electrons carry charge=

If n electrons are involved in the reaction, the passage of n Faradays i.e  of electricity will liberate 1 mole or molecular mass of the substance.

1 Faraday or 96500 C of electricity will liberate=\frac{\text {molecular mass}}{\text {n}}={\text {Equivalent mass}} of the substance.

Cu^{2+}+2e^-\rightarrow Cu

1 faraday deposit = 1 g equivalent

5 faraday will deposit =\frac{1}{1}\times 5= 5g equivalent
