What is Molar Mass?

Molar mass is the mass of one mole of a given substance. For elements, it is the atomic weight found on the periodic table. For compounds, it is the sum of the atomic weights of all atoms in the chemical formula.

How to use this calculator:

Enter a formula like H2O for water.
For complex compounds, use parentheses: Ca(OH)2.
Ensure chemical symbols are correctly capitalized (e.g., NaCl, not nacl).

Molar mass is expressed in grams per mole (g/mol).
