In the electrolysis of water,one Faraday of electrical energy would evolve

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 $= 40 \ g \ mol^{-1}$)

When a current of $10 \ A$ is passed through molten $AlCl_{3}$ for $1.608 \ minutes$,the mass of $Al$ deposited will be [Atomic mass of $Al = 27 \ g/mol$]:- (in $g$)

Faraday's laws of electrolysis are related to

How much time (in $sec$) is required to coat a metal surface of $80 \, cm^2$ with a $0.005 \, mm$ thick layer of silver from a silver nitrate solution using a current of $3 \, A$? (Density of silver $= 10.5 \, g \, cm^{-3}$)

What is achieved by Faraday using the principles of electrolysis?
