Answer 2

The Avogadro number is the number of constituent particles (usually molecules, atoms or ions) that are contained in one mole, the international (SI) unit of amount of substance: by definition, exactly 6.02214076×1023, and it is dimensionless.It is named after the scientist Amedeo Avogadro (1776–1856).
