  • A mole (mol) is a measure of the number of particles (atoms, ions or molecules) contained in a substance.
  •  One mole of any substance (element or compound) contains the same number of particles - six hundred thousand billion billion or 6.02 x 1023.
    This value is known as the Avogadro constant.
  • The mass of one mole of a substance is its relative atomic mass or relative formula mass in grams.
