Moles

2,000 mmol · 1.2044e+24 particles
Moles are mass divided by molar mass, and everything else follows. A mole is Avogadro's number of particles — 6.02214076 × 10²³ exactly, a defined value since the 2019 SI redefinition rather than a measurement. That is why the particle count here carries no more uncertainty than the mass you typed.
How the Moles to Grams Calculator works
Moles are mass divided by molar mass, and the particle count follows from Avogadro's number — which has been exactly 6.02214076 × 10²³ since the 2019 SI redefinition, a defined value rather than a measurement.

Frequently asked questions
How do I convert grams to moles?
Divide the mass by the molar mass. 36.03 g of water divided by 18.015 g/mol is 2 moles.
How do I convert moles to grams?
Multiply by the molar mass. Two moles of water is 2 × 18.015 = 36.03 g.
How many particles are in a mole?
6.02214076 × 10²³ exactly. Since 2019 the mole is defined as that number of entities, so the constant carries no experimental uncertainty.
