Grams to Moles Calculator
Convert mass to moles and molecules for any chemical compound. Select a substance or enter custom molar mass to get instant results.
Step 1: Mass Input
50.0 g
Understanding moles
One mole contains exactly 6.02214076×10²³ elementary entities (Avogadro’s number). The molar mass is the mass of one mole of a substance in grams/mol.
Step 2: Compound
58.44 g/mol
Avogadro’s constant
6.02214076 × 10²³ molecules per mole. The number of molecules is calculated as moles × Avogadro’s number.
