Lesson 4: Calculating the Volumes of Gases

Last lesson we looked at at the atmosphere as it is today and looked at two methods for determining the composition of the atmosphere.
In this lesson we will see and learn how to do the calculations that scientists use to determine the volumes of gases. This is a simplified version of these types of calculations as my students had not yet come across moles or relative formula mass.

This lesson is delivered over YouTube but has some accompanying resources.

I teach the AQA GCSE Chemistry course, including both double (8464) and triple (8462) award, and as such most of these resources will be specific to that course, however they may also be useful for other specifications.
