A good understanding of percentages is important for the chemist as it is used in several different branches of chemistry such as formulation and calculations including reaction yields and empirical formulae. Percentages can be easily presented in a visual way which also benefits the visual learner.

After working through this topic you will be able to:

  • understand the links between percentages, fractions and ratios;
  • apply percentages to a chemical context; and
  • use strategies to help learners improve their confidence when working with percentages.
