Molar Mass Result

Enter a chemical formula to calculate its molar mass.

Description

Molar mass is the mass of one mole of a substance, expressed in g/mol. It is calculated by summing the atomic masses of all atoms in the chemical formula. Molar mass is essential for converting between mass and moles in stoichiometric calculations.

How to use

Enter a chemical formula using element symbols and numbers (e.g. H2O, NaCl, C6H12O6). Parentheses are supported for groups, e.g. Ca(OH)2 or Fe2(SO4)3. The molar mass and element breakdown are computed instantly.
