About Molar Mass

Molar mass is the mass of one mole of a substance, expressed in grams per mole (g/mol). It is calculated by summing the atomic masses of all atoms in a chemical formula.

Key Concepts:

  • Mole: Unit of measurement for amount of substance (6.022 × 10²³ particles)
  • Atomic Mass: Mass of a single atom, measured in atomic mass units (amu)
  • Molar Mass: Mass of one mole of a substance in grams
  • Molecular Weight: Sum of atomic weights in a molecule

Common Atomic Masses:

  • Hydrogen (H): 1.008 g/mol
  • Carbon (C): 12.011 g/mol
  • Nitrogen (N): 14.007 g/mol
  • Oxygen (O): 15.999 g/mol
  • Sodium (Na): 22.990 g/mol
  • Chlorine (Cl): 35.453 g/mol

Applications:

  • Stoichiometry calculations
  • Solution concentration preparation
  • Chemical reaction balancing
  • Laboratory measurements
  • Industrial chemical processes
