About Molar Mass

Molar mass is the mass of one mole of a substance, measured in grams per mole (g/mol). It is calculated by summing the atomic masses of all the atoms in a molecule.

How to Use

Enter the chemical formula using element symbols (e.g., C for carbon, H for hydrogen). Use numbers for subscripts (H2O). Parentheses are supported for groups (e.g., (CH3)2CO).

Important Notes

• Element symbols are case-sensitive (Co is cobalt, CO is carbon monoxide)

• Use standard notation for formulas

• The calculator uses the latest IUPAC atomic weights

Applications

Molar mass calculations are essential in chemistry for stoichiometry, preparing solutions, determining empirical formulas, and many other chemical calculations.
