Understanding Avogadro's Number

Formula

Avogadro's number (6.02214076 x 10²³) is the number of entities in one mole of any substance. Named after Italian scientist Amedeo Avogadro, it is one of the fundamental constants of chemistry.

This constant allows chemists to convert between the number of individual atoms or molecules and the macroscopic amount in moles. One mole of any element contains exactly this many atoms, regardless of the element.

Common use cases:

  • Particle count estimation
  • Mole-to-mass conversions
  • Understanding atomic-scale quantities
