In your science experiments, often you need to know how much material to use or how much of a solute is present in a solution. This applies particularly to biology and chemistry experiments. Almost certainly you will need to do some calculations!

This survival guide should help you to do these calculations. It looks closely at how to handle numbers correctly, how to express concentrations and how to calculate dilutions. There are plenty of worked examples to guide you, then lots of questions (with answers) for you to practise your skills.
