Introduction:

Mole is defined as the unit which is used for measurement in the international system of units for amount of substance. One mole is always equal to the Avogadro’s number that is $6.02\times {10}^{23}$. At constant pressure and temperature, equal volume of gases contains equal numbers of molecules. The charge carried by one mole is called $1\text{Faraday}$.
