Help your students check or revise key calculations in chemistry, including relative formula mass, using this lesson plan with activities for 14–16 year olds.

This activity enables students to check and practise simple calculations in chemistry. As groups of students become ‘expert’, demonstrating their ability to their peers and their teacher, they progressively validate the work of other groups.

Students will practise:

Calculating the relative formula mass of a compound given its formula and appropriate atomic masses.
Calculating the percentage of an element from a given formula.
Calculating masses of reactants and products from balanced equations.
