Molar Mass Calculator
Molar Mass Calculator
Enter a chemical formula (e.g., H2O, CO2) to calculate its molar mass.
What is molar mass?
Molar mass is the mass of one mole of a substance, expressed in grams per mole (g/mol). It equals the sum of atomic masses of all atoms in the molecule.
How to use the calculator?
Enter the chemical formula using proper notation:
- Element symbols: H, O, C, Na, Cl, etc.
- Numbers after elements: H2O, CO2, CaCl2
- Parentheses for complex compounds: Ca(OH)2, Al2(SO4)3
Examples:
- H2O (water) = 18.016 g/mol
- NaCl (salt) = 58.44 g/mol
- CO2 (carbon dioxide) = 44.01 g/mol
- CaCO3 (calcium carbonate) = 100.09 g/mol
Applications:
- Stoichiometric calculations
- Solution preparation
- Laboratory work
- Chemical analysis
