Understanding Relative Formula Mass is critically important when attempting all calculations in Chemistry.

In this class, students will learn how to calculate relative formula mass. They will then use these calculations to find out concentrations of solution and uncertainties in measurements. 

This is a challenging topic in Chemistry which needs a lot of practise so before beginning the class please make sure you have access to the Periodic Table and a calculator so you can follow along with your teacher in completing calculations.
