The mole is the central hub

Amount of substance map linking moles to mass, particles, solution concentration, gas data, and balanced equation mole ratios

Chemical calculations look varied, but the method is usually the same. Convert what you are given into moles, use the balanced equation ratio, then convert to the unit you need.

Step-by-step lessons on Eduqas A Level Chemistry Chemical calculations. Each one builds up to exam-style questions. Build confidence with atomic structure, bonding and moles calculations early on, since these underpin the more demanding organic mechanisms, equilibrium and practical-analysis topics that dominate Year 2.
