A predicted maximum
The theoretical mass is the maximum mass of product possible if all of the limiting reactant reacts and no product is lost. It is calculated from a balanced equation, not measured in the laboratory.
Step-by-step lessons on AQA GCSE Chemistry 3.3.1b Theoretical mass of a product. 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.
