Frequently asked questions

Multiply the moles by Avogadro's number, 6.022 × 10²³. One mole contains that many particles.

It counts particles — atoms for an element, or molecules or formula units for a compound.

Atoms are tiny, so even a small, weighable sample contains an enormous number of them — hence the huge constant.

Divide the number of particles by Avogadro's number to find the moles.

The Moles to Atoms Calculator uses the formula: Number of particles = Number of moles × 6.022e23. For example, with number of moles of 1 mol, the number of particles is 602,200,000,000,000,027,262,976.
