Question
If a reaction produces 30 g of product from a theoretical yield of 60 g, what is the percentage yield?
Answer
The answer is 50 %.
Explanation
This uses Percentage Yield because the objective is about (chemistry only) Explain why some product may be lost when separated from a reaction mixture. The reasoning belongs to Percentage yield within Yield and atom economy of chemical reactions (chemistry only), so it should not be confused with nearby quantitative ideas such as mass, moles, concentration, yield, atom economy, or gas volume unless those are named in the objective. Use the focus term chemistry only to keep the answer aligned with AQA GCSE Chemistry 8462 Unit 4.3.
Common mistake
Product Loss Explanation
Students often state that product loss occurs only due to incomplete reactions.
Emphasize that product loss can also happen during separation processes, such as filtration or evaporation, and not just from the reaction itself.
