Balanced equations give mole ratios
Balanced equations give mole ratios
Stoichiometry describes the ratio of the amounts in moles of reactants and products. The balancing numbers, also called coefficients, give this ratio.
Step-by-step lessons on OCR GCSE Chemistry 3.1.6 Stoichiometry, limiting reactants and reacting masses. 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.
