Frequently asked questions

Divide the number of particles by Avogadro's number, 6.022 × 10²³. That many atoms is exactly 1 mole.

It is 6.022 × 10²³, the number of particles in one mole of any substance.

Yes. A mole counts any particles — atoms, molecules or ions — using the same Avogadro's number.

Multiply the moles by Avogadro's number to get the number of particles.
