A mole is the amount of a substance that contains the same number of molecules or other elementary units as the number of atoms in 0.012 kilograms (12 grams) of carbon 12. Just as a dozen always contains twelve items, a mole always contains 6.022x1023 items. This value is known as Avogadro's number. Moles are a convenient unit for discussing chemical reactions, because typical reactions can have huge amounts of atoms, but only a few moles.
A Mole is also a small, underground dwelling mammal of the family Talpidae.
