How much charge in coulombs is required for the reduction of one mole of $Al^{3+}$ to $Al$?

The number of electrons involved in redox reactions when $1$ Faraday of electricity is passed through an electrolyte in solution is

If solutions of silver nitrate and cupric salt are connected in series and the same current is passed,what will be the weight of copper deposited in $gm$ when $1.08 \ g$ of silver is deposited?

$1$ mole of electrons corresponds to how much Faraday,how much Coulomb,and how many electrons?

An acidic solution of dichromate is electrolyzed for $8 \ min$ using $2 \ A$ current. As per the following equation: $Cr_{2}O_{7}^{2-} + 14H^{+} + 6e^{-} \rightarrow 2Cr^{3+} + 7H_{2}O$. The amount of $Cr^{3+}$ obtained was $0.104 \ g$. The efficiency of the process (in $\%$) is (Take: $F = 96000 \ C$,At. mass of chromium $= 52$)

The relation between Faraday constant $(F)$,chemical equivalent $(E)$,and electrochemical equivalent $(Z)$ is
