About Molar Mass

Molar mass is the mass of one mole of a chemical compound, measured in grams per mole (g/mol). It is calculated using the atomic masses of all atoms in the compound.

How This Calculator Works

The calculator parses your chemical formula, counts the number of each element, and sums their atomic masses. It also provides a breakdown of each element's contribution.

Tips & Advice

Use correct chemical notation, including capitalization and numbers. Parentheses are supported for groups, e.g., Al2(SO4)3.

FAQs

Can I enter ions? Only neutral compounds.
Are parentheses supported? Yes, nested groups are supported.
How accurate is the result? Based on standard atomic masses, good for general chemistry use.
