⚗️ Molar Mass Calculator
Calculate molar mass from a formula
Enter a formula using element symbols and counts (e.g. H2SO4)
How Molar Mass Calculation Works
- 1Enter a chemical formula like H2O, NaCl, or Ca(OH)2.
- 2The tool parses the formula and looks up atomic masses from the periodic table.
- 3Each element's mass is multiplied by its count and summed to give the total molar mass in g/mol.
About Molar Mass Calculator
Calculate the molar mass of any chemical compound from its formula. Supports all elements, hydrates, and complex formulas.
Frequently Asked Questions
Does it handle parentheses?
Yes. Formulas like Ca(OH)2 and Mg3(PO4)2 are parsed correctly, distributing subscripts across grouped elements.
Where do the atomic masses come from?
Standard atomic weights from the IUPAC periodic table are used for all calculations.
