  • Masses of Substances
    • Relative Atomic Mass
      • mean mass of an atom of an element compared to 1/12 of the mass of Carbon-12.
    • Relative Molecular Mass
      • the sum of the relative atomic masses of all the atoms in a compound.
        • used for molecules of elements and compounds
      • Relative Formula Mass
        • includes both molecules and ions
          • should be used for compounds with giant structures
    • Amount of Substances (moles)
      • Avogadro's Constant (L) = 6.02x10^23
    • Molar Mass (M)
      • mass per mole of any substance
        • unit: g/mol
    • n=m/M
