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

$10 \, A$ current is passed through $CuSO_4$ solution for $193 \, \text{minutes}$ at $1 \, \text{bar}$ pressure and $300 \, K$ temperature. If the cell has $80 \%$ efficiency,find the weight of $Cu$ deposited and the volume of $O_2$ evolved. $[Cu = 63.5 \, u, R = 0.08314 \, \text{L bar K}^{-1} \text{mol}^{-1}]$

How many electrons flow when a current of $5 \ A$ is passed through a cell for $200 \ s$?

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 $g$)?

Three electrolytic cells $A, B, C$ containing solutions of $ZnSO_{4}, AgNO_{3}$ and $CuSO_{4}$ respectively are connected in series. $A$ steady current of $1.5 \ A$ was passed through them until $1.45 \ g$ of silver deposited at the cathode of cell $B$. How long did the current flow? What mass of copper and zinc were deposited?

When $1 \ C$ of charge is passed through an electrolyte solution,the mass deposited is equal to:
