The quantity of electricity required for the complete electrolysis of $2 \ mol$ of $Na^{+}$ is = ....... Coulombs.

The number of moles of electrons passed when a current of $2 \ A$ is passed through a solution of electrolyte for $20 \ minutes$ is

If nearly $10^5 \ C$ liberate $1 \ gm$ equivalent of aluminium,then the amount of aluminium (equivalent weight $9$) deposited through electrolysis in $20 \ minutes$ by a current of $50 \ A$ will be .............. $gm$.

In the electrolysis of a $CuSO_4$ solution,how many grams of $Cu$ are plated out on the cathode,in the time that is required to liberate $5.6 \ L$ of $O_{2(g)}$,measured at $1 \ atm$ and $273 \ K$,at the anode (in $g$)?

Faraday has the dimensions of

The value of one Faraday is .............. $C \ mol^{-1}$.
