About Molar Mass
Molar mass is the mass of one mole of a substance, expressed in grams per mole (g/mol). It's calculated by summing the atomic masses of all atoms in a molecule.
Molar Mass = Σ(Atomic Mass × Number of Atoms)
Common applications:
- Converting between mass and moles
- Calculating solution concentrations
- Stoichiometric calculations
- Determining empirical and molecular formulas
Example - Water (H₂O):
2 × 1.008 + 1 × 15.999 = 18.015 g/mol
Molar mass is fundamental in chemistry for quantitative analysis, reaction stoichiometry, and solution preparation.
