Molar Mass Calculator
Enter a chemical formula to compute its molar mass (g/mol).
| Element | Count | Atomic mass | Subtotal |
|---|---|---|---|
| H Hydrogen | 2 | 1.008 | 2.02 |
| S Sulfur | 1 | 32.06 | 32.06 |
| O Oxygen | 4 | 15.999 | 64.00 |
Atomic masses are standard atomic weights. Parentheses and hydrate dots (·) are supported (e.g. CuSO4·5H2O).
How to use
- 1
Type a chemical formula. Element symbols are case-sensitive (Na, Cl).
- 2
The total molar mass and a per-element breakdown appear instantly.
- 3
Use the example buttons, or enter parentheses Ca(OH)2 and hydrates CuSO4·5H2O.
FAQ
Is this tool free?
Yes — it is completely free to use, with no account or sign-up required.
What is this tool?
Enter a chemical formula and this tool computes its molar mass (molecular weight, g/mol). Type something like H2SO4 or C6H12O6 and it shows the total along with each element's count, atomic mass, and subtotal in a table. Parentheses (Ca(OH)2) and hydrate dots (CuSO4·5H2O) are recognized, and atomic masses are the standard atomic weights from the periodic table. Element symbols are case-sensitive (Na, Cl), and everything runs in your browser, free with no install.
