This video is a breakdown of the equations you should know for the A Level Chemistry Amount of substance topic 3.1.2 for the AQA exam board. This is more of a revision video so be sure to do lots of past paper questions! It includes moles, mass, molar mass (Mr), concentration, volume, mass concentration, ideal gas PV=nRT, mass concentration, dilutions, percentage yield and percentage atom economy.

I go through the the equations themselves and their units, and give some extra information/explanations that I find relevant.
