When $X$ amperes of current is passed through molten $AlCl_3$ for $96.5$ $s$,$0.09$ $g$ of aluminium is deposited. What is the value of $X$?

When $4.5 \, A$ current is passed through $1 \, L$ of $0.6 \, M$ $CuCl_2$ solution for $1.15 \, hour$,calculate the mass of $Cu$ and the change in concentration of the solution. $[Cu = 63.5 \, u]$

The charge required for the reduction of $1 \ \text{mole}$ of $MnO_4^{-}$ to $MnO_2$ is (in $F$)

$3.17 \ g$ of a substance is deposited by a current of $0.1 \ mol$ of electrons. What is the equivalent weight of the substance?

$2.644 \ g$ of metal $(M)$ was deposited when $8040 \ C$ of electricity was passed through molten $MF_2$ salt. What is the atomic mass of $M$ $(F = 96500 \ C \ mol^{-1})$ (in $u$)?

In an industrial process,$40 \ kg$ of calcium is produced by electrolysis in $2 \ hours$. How much $kg$ of aluminum would be produced if the same current is passed for the same duration? (Atomic mass of $Ca = 40, Al = 27$)
