In this GCSE Chemistry video, we look at how to calculate the percentage by mass of an element in a compound. This is a relatively straightforward topic but it’s very important that you can do it.

This is the first in my new style of videos. Animated videos are much quicker to make than ones with me in it so with these, I can make more videos to help more students. I would appreciate your feedback, ideally constructive.
