A solution is a mixture formed when a solute dissolves in a solvent. Molar concentration tells you how many moles of solute are present in every cubic decimetre of solution.
Step-by-step lessons on AQA GCSE Chemistry 3.4 Using concentrations of solutions in mol/dm³ (HT only), covering 3.4 Using concentrations of solutions in mol/dm³ (HT only). Each one builds up to exam-style questions. Nail the core quantitative topics — moles, balancing equations and calculations — early on, since they underpin higher-tier questions across every paper and topic.
