Theoretical yield
The theoretical yield is the maximum mass of product that could form from the limiting reactant. It assumes the reaction goes to completion, no product is lost, and all other reactants are present in excess.
Step-by-step lessons on OCR GCSE Chemistry 5.1.2 Theoretical mass, percentage yield and atom economy. 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.
