Molecular Weight Calculator
Enter a chemical formula (e.g. H2O, NaCl, H2SO4) to calculate molecular weight (g/mol).
How to Use
- Element symbols start with a capital letter. e.g. H, He, Na, Cl
- Subscript numbers follow immediately after the symbol. e.g. H2O, CO2
- Supported elements include H, C, N, O, Na, Cl, S, Fe, Ca, Cu, Zn and ~30 more
HโO โ Hร2 + Oร1 = 2ร1.008 + 15.999 = 18.015 g/mol
NaCl โ Naร1 + Clร1 = 22.990 + 35.453 = 58.443 g/mol
HโSOโ โ Hร2 + Sร1 + Oร4 = 98.079 g/mol
