The quantity of current required to deposite one mole of Mg from Mg2+ electrolyte is two faradays as follows:
Mg2++2e−→Mg
The amount of electricity needed is equal to 2F,
From the above statement, we can conclude that one faraday is equal to the charge on one mole of electrons.
Therefore, both (A) and (R) are correct and (R) is the correct explanation of (A)
