Molecular Weight Calculator
Now fully fixed for complex formulas (including nested parentheses)
Enter a formula to calculate
Important: Use standard chemical notation:
• Element symbols start with uppercase letter (e.g., Na not na, Cl not cl)
• Second letter lowercase if present (e.g., Co for cobalt, not CO)
• Supports complex/nested formulas and hydrates with · (dot)
• Examples that now work perfectly:
- CO2 (carbon dioxide)
- NaOH
- CuSO4·5H2O (copper sulfate pentahydrate)
- Al2(SO4)3
- (NH4)2Fe(SO4)2·6H2O (Mohr's salt)
