In chemistry, mol, from the German mol “small mass” (Nernst, 1895), aka “gram mol” (or g-mol) or “gram molecule” (Ostwald, 1893), is the base unit of mass in laboratory-scale chemical reactions, defined as the amount of substance that contains an Avogadro number of elementary units, equivalent to the number of atoms in a 12 gram sample of carbon 12.[1]
