Essential Chemistry for IGCSE - Chemical Calculations (Section 2 - No. 5)
In a chemical reaction, if the theoretical yield of a product is 50g, and the actual yield is 40g, what is the percentage yield?
10%
20%
80%
90%
Explanation
Percentage yield = (Actual Yield / Theoretical Yield) * 100 = (40g / 50g) * 100 = 80%
