What is the total charge of one mole of electrons?

The time required (in hours) to reduce $3 \ mol$ of $Fe^{3+}$ ions to $Fe^{2+}$ ions with $2.0 \ A$ of current is $\left(1 \ F = 96500 \ C \ mol^{-1}\right)$ (in $.2$)

$96500 \ C$ of electric charge liberates how many grams of $Cu$ from $CuSO_4$ solution?

$A$ solution of $Ni(NO_{3})_{2}$ is electrolysed between platinum electrodes using a current of $5 \, A$ for $20 \, minutes$. What mass of $Ni$ is deposited at the cathode (in $, g$)?

How many Faraday of electricity is required to deposit $0.8 \ g$ of calcium at cathode by the electrolysis of $CaCl_2$ (in $F$)?

$A$ $200 \ W, 100 \ V$ bulb is connected in series with an electrolytic cell. If an aqueous solution of an $Sn$-salt is electrolysed for $5 \ hrs$,$11.1 \ g$ of $Sn$ gets deposited. The chemical formula of the compound is (Given atomic weight of $Sn$ is $118.7 \ g \ mol^{-1}$).
