Amount of substance (AoS) is a measure of the number of particles contained within a given quantity of a solid, liquid or gas.

The SI unit for measuring the amount of substance is the mole (mol).  A mole is defined as a quantity of substance made up of exactly 6.02214076×10²³ (Avogadro constant) particles. A particle can be an atom, molecule, ion, proton, neutron, electron or any other sub-atomic particle.

In addition to the mole and number of particles, there is another group of units used to define the amount of substance which is based on the mass of carbon-12 isotope, where 1 gram-mole is equal to the number of atoms in 12 grams, and likewise 1 kilogram-mole  is equal to 12 kilograms, and 1 pound-mole is equal to 12 pounds. 12 grams of carbon-12 contain 6.02214076×10²³ (Avogadro constant) atoms, therefore one gram-mole equals exactly one mole.
