What amount of $Cl_2$ gas is liberated at the anode if $1 \ A$ current is passed for $30 \ min$ through an $NaCl$ solution?

Mass in grams of copper deposited by passing $9.6487 \ A$ current through a voltmeter containing copper sulphate solution for $100 \ s$ is (Given : Molar mass of $Cu: 63 \ g \ mol^{-1}, 1 \ F=96487 \ C$ ) (in $g$)

$A$ $4 \ A$ current is passed through a solution of zinc sulphate for $50 \ min$. Find the amount of zinc deposited at the cathode in $g$.

The quantity of electricity required to deposit $1$ gram-equivalent of a substance at an electrode is equal to .......

On passing $C$ ampere of current for time $t$ seconds through $1 \ L$ of $2 \ M$ $CuSO_4$ solution (atomic weight of $Cu = 63.5$), the amount $m$ of $Cu$ (in grams) deposited on the cathode will be:

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