KS5 Chemistry: The Mole and The Avogadro Constant (AS Level)

Whole lesson including starter activity, main work task and answers on Avogadro’s constant and calculating moles using the mole equation

The lesson begins with a 5-10 minute starter task (DO NOW) on previous KS5 knowledge about relative atomic mass of elements and calculating the relative molecular mass of compounds

By the end of this lesson KS5 students should be able to:

  1. Know that the Avogadro constant is the number of particles in a mole
  2. Calculate the number of moles present in a given mass of an element or compound using the mole equation
  3. Rearrange the mole equation to calculate either the number of moles, Mr or mass of an element or compound

The teacher will be able to check students have met these learning objectives through mini AfL tasks for students to complete as well as a 20-30 minute independent work task

All tasks have worked out answers which will allow students to self assess their work in the lesson
