Moles to Atoms / Molecules Calculator
Convert between moles and the number of representative particles (atoms, molecules, or ions) using Avogadro's number.

Miten tämä laskin toimii?
Multiply the amount of substance in moles by Avogadro's number (6.02214076 × 10²³ /mol) to get the number of particles: N = n × Na. To go the other way, divide the particle count by Avogadro's number to find moles. The same factor works for atoms, molecules, and ions alike.

How this is calculated
Pick a direction. For moles → particles, enter the amount of substance in moles (n); the calculator multiplies by Avogadro's number, Na = 6.02214076 × 10²³ per mole, to get the count of particles N. For particles → moles, enter the number of particles N and the calculator divides by Na to recover the amount of substance in moles.
The single relationship behind both directions is N = n × Na. "Particles" is generic: depending on the substance it may mean atoms (for monatomic elements), molecules (for molecular compounds), or formula units / ions (for ionic compounds). The conversion factor is identical regardless of which particle is being counted.
Moles are entered in mol and particle counts are pure (dimensionless) numbers. Because Avogadro's number is enormous, particle counts are shown in scientific notation. Values must be non-negative and finite; very large inputs are still reported exactly via the N = n × Na product.
Usein kysytyt kysymykset
Avogadro's number is the number of representative particles in one mole, defined exactly as 6.02214076 × 10²³ per mole since the 2019 SI redefinition.
Yes. One mole always contains Avogadro’s number of whatever the representative particle is — atoms, molecules, or formula units — so the same factor converts all of them.
Switch the direction to particles → moles and the calculator divides your particle count by Avogadro’s number, giving the amount of substance in moles.
