How many electrons are involved in the reaction when $0.40 \ F$ of electricity is passed through an electrolytic solution?

When a current of $9.65 \ A$ is passed for $10 \ \text{minutes}$,$3.0 \ g$ of metal is deposited. What is the equivalent weight of the metal?

How many faraday of electricity are required to deposit $10 \ g$ of calcium from molten calcium chloride using inert electrodes (in $F$)? (Molar mass of calcium $= 40 \ g \ mol^{-1}$)

How long should aqueous $NaCl$ be electrolysed by passing $100 \ A$ current,so that $0.5 \ mol$ chlorine is released at anode?

Salts of $A, B$ and $C$ were electrolysed under identical conditions using the same quantity of electricity. It was found that when $2.1 \ g$ of $A$ was deposited,the weights of $B$ and $C$ deposited were $2.7 \ g$ and $9.6 \ g$. If the atomic mass of $A, B$ and $C$ are $7, 27$ and $64$ respectively,then the valencies of $A, B$ and $C$ respectively are:

Faraday's laws of electrolysis are related to
