What is amount of substance?
The amount of substance counts particles (atoms, molecules, ions) in batches large enough to weigh. Its SI unit, the mole, contains exactly 6.02214076 × 10²³ entities, Avogadro's number. One mole of a substance has a mass in grams equal to its molecular mass in daltons: a mole of water weighs about 18 g, a mole of carbon-12 exactly 12 g.
Chemical engineers in the US also use the pound-mole: the amount whose mass in pounds equals the molecular mass, 453.59237 moles.
