Lesson overview:Relative formula mass (HT only)

  • Use the periodic table and formulae to determine the relative formula mass of compounds
  • Work out percentage of given elements in a compound
  • Work out the mass of a particular element in a given mass of a compound
  • Use the periodic table and formulae to determine the relative formula mass of compounds
  • Work out percentage of given elements in a compound
  • Work out the mass of a particular element in a given mass of a compound

This lesson will recap briefly on relative atomic mass and students will calculate relative formula mass and percentage composition of an element in a compound. Students will also be able to work backwards and work out the mass and name of a metal in a compound using the relative formula mass.
