In $CuSO_4$ solution,when an electric current equal to $2.5 \ F$ (faraday) is passed,the number of $gm$ equivalents deposited on the cathode is:

Charge required to liberate $11.5 \ g$ of sodium is:

The Avogadro's number is $6 \times 10^{23} \ \text{mol}^{-1}$ and the electronic charge is $1.6 \times 10^{-19} \ \text{C}$. The Faraday's constant $(F)$ is given by:

The ratio of weights of hydrogen gas liberated and magnesium deposited by passing the same amount of electricity from aqueous $H_2SO_4$ and fused $MgSO_4$ are :
