Mole, standard unit (6.02214076 x 10^23) in chemistry for measuring large quantities of very small entities such as atoms, molecules, or other specified particles. The number of units in a mole also bears the name Avogadro’s number, or Avogadro’s constant, in honor of the Italian physicist Amedeo Avogadro.
