Das Mol (Einheitenzeichen: mol) ist die SI-Einheit der Stoffmenge. Sie dient unter anderem der Mengenangabe bei chemischen Reaktionen. Ein Mol eines Stoffes enthält definitionsgemäß exakt 6.02214076e23 (602 Trilliarden) Teilchen (Avogadro-Konstante). Die Zahl wurde so festgelegt, dass x Gramm von Teilchen mit einer Masse von x atomaren Masseneinheiten möglichst genau 1 mol sind. Teilchenzahl und Stoffmenge sind somit einander direkt proportional; jede dieser beiden Größen kann als Maß für die andere dienen.
