Percentage yield
What is Percentage yield?
Percentage yield is the mass of product actually obtained divided by the maximum mass the balanced equation predicts from the limiting reactant, multiplied by 100 per cent.
This definition is part of the Stoichiometry chapter in Cambridge IGCSE Chemistry.
Common mistakes with Percentage yield
- "Percentage yield = theoretical ÷ actual." Fix Actual on top. What you got is being compared with what was possible, so the possible amount is the whole.
