mole (animal) gets the sentence: A '''Mole''' is also a small, underground dwelling mammal of the family ''Talpidae''.
A '''mole''' is the amount of a substance that contains the same number of [[molecule]]s or other [[element]]ary 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 6.022x10<sup>23</sup> 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.
