In 1 mol of any substance, there are $6.022\times {10}^{23}$ units of that substance. These units can be atoms and molecules. The number of units in 1 mol of any substance is known as Avogadro’s number. It is denoted by symbol N_A.

Thus, mol is used to represent the amount of large amount of units.

Similar to moles, dozen is used to represent the amount which is equal to 12 units.
