How to calculate mass from moles
This calculator finds the mass of a substance from its molar amount and molar mass — a fundamental stoichiometry conversion.
How the calculation works
Mass = Moles × Molar mass.
Example
2.5 moles of a substance with a molar mass of 58.44 g/mol (like NaCl): 2.5×58.44 = 146.1 g.
