How many coulombs of electricity is required to produce $1 \ g$ of $Na$ metal from its ions (in $C$)? (Atomic mass of $Na = 23 \ g/mol$)

Which is the weight of $Al$ deposited at cathode when $1 \ A$ current is passed through molten $AlCl_3$ for $9650 \ s$ (in $g$)?
(Atomic mass of $Al = 27$)

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 $g$)?

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

When an electric current is passed through acidified water,$112 \ mL$ of hydrogen gas at $N.T.P.$ was collected at the cathode in $965 \ seconds$. The current passed,in ampere,is

The density of $Cu$ is $8.94 \, g \, cm^{-3}$. The quantity of electricity needed to plate an area $10 \, cm \times 10 \, cm$ to a thickness of $10^{-2} \, cm$ using $CuSO_4$ solution would be,if atomic mass of $Cu$ is $63.5$ .................. $C$
