The mole is a unit of dimension or measurement used in chemistry theory to calculate amounts of a chemical substance, defined as an amount of a substance which contains as many elementary entities (e.g., atoms, molecules, electrons, ions) as there are atoms in 12 grams of pure carbon-12 (12C), the isotope of carbon with atomic weight 12. This corresponds to a value of 6.02214179(30)×1023 elementary entities of the substance. This is one of the base units in the International System of Units ISU, and has the unit symbol mol.
The mole is broadly used in chemistry, in its place of units of mass or volume, as a convenient way to express the amounts of reactants & products of chemical reactions.
