  1. Avagadro constant
    6.02 x 1023
  2. Relationship between moles and mass
    • Number of moles (mol) = Mass (g) / Molar Mass (Mr)
    • OR
    • n = m / Mr
  3. Relationship between moles and number of atoms
    • Number of moles (mol) = Number of atoms / Avagadro constant (6.02 x 1023)
    • OR
    • n = atoms / 6.02 x 1023
  4. 'Moles in solution' equation
    • Number of moles (mol) = Volume (dm3) x Concentration (moldm3)
    • OR
    • n = Vol x C
  5. 'Moles from volume of gas' equation
    • Number of moles (mol) = Volume (dm3) / 24dm3
    • OR
    • n = Vol / 24
