Introduction

Aims and Objectives

The aims of this learning object are to:

• familiarise you with basic calculations required in solution chemistry
• provide an easy-to-access resource that you can use to refresh your knowledge whenever you need it

By the end of this lesson you should be able to:

• manipulate simple equations in a variety of units
• use given information to calculate unknowns in solution chemistry
• devise methods to achieve solutions of a desired concentration
• handle calculations in solution chemistry with confidence

To use this resource effectively, it will help if you are familiar with:

• Relative molecular mass
• Arithmetic operations i.e. addition, subtraction, multiplication, division

Requirements

You may need a calculator to attempt exercises in some topics.

Your computer should have audio enabled as videos in this resource contain sound.
