On passing $96500 \ C$ of charge through a $CuSO_4$ solution,the amount of copper liberated is:

The number of Faraday required to generate $1$ $g$ $atom$ of $Mg$ from $MgCl_2$ is :-

How much current should be passed through acidified water for $100 \ s$ to liberate $0.224 \ L$ of $H_2$ gas at $STP$ (in $A$)?

On passing $3 \ A$ of electricity for $50 \ minutes$,$1.8 \ g$ of metal deposits. The equivalent mass of the metal is:

When electric current is passed through acidified water for $1930 \,s$, $1120 \,mL$ of $H_2$ gas is collected (at $STP$) at the cathode. What is the current passed in amperes?

What is the amount of chlorine evolved when $2 \ A$ of current is passed for $30 \ min$ in an aqueous solution of $NaCl$ (in $g$)?
