In laboratory experiments it is crucial to make up solutions of the correct concentration, and to be able to calculate how much of a particular component is present. This section gives you practice in three of the types of calculation involved:

The third type of calculation is perhaps the most difficult, so we have also provided a version that breaks it up into three stages:
