Molar Mass Calculator
Calculate the molar mass of a chemical compound from its formula, e.g. H2O, C6H12O6 or Ca(OH)2.
Enter your values and press Calculate.
How to use the Molar Mass calculator
Element symbols are case-sensitive: Co is cobalt, CO is carbon monoxide. Brackets are supported, e.g. Mg(OH)2.
Formula
Molar mass = Σ (atomic mass × number of atoms), using IUPAC standard atomic weights.
