The molecular formula for niacin is given to be ${\text{C}}_{\text{6}}{\text{H}}_{\text{5}}{\text{NO}}_{\text{2}}$. The number of molecules in $14\text{mg}$ dose of niacin.

Introduction:

Mole is defined as the unit that is used for measurement in the international system of units for measuring the amount of a 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 number of molecules. The charge carried by one mole is called $1\text{Faraday}$.
