What amount of electricity can deposit $1 \ mole$ of $Al$ metal at cathode when passed through molten $AlCl_3$?

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

What is the charge required for the reduction of two moles of $Cu^{2+}$ to $Cu$?

$A$ current of $3 \ A$ is passed through a molten calcium salt for $1 \ hr \ 47 \ min \ 13 \ s$. The mass of calcium deposited is $(Molar \ mass \ of \ Ca = 40 \ g \ mol^{-1})$ (in $g$)

$A$ current $I$ is passed for a time $t$ through a number of voltameters. If $m$ is the mass of a substance deposited on an electrode and $z$ is its electrochemical equivalent,then

The mass of a substance liberated when a charge $q$ flows through an electrolyte is proportional to
