Percent yield calculator
Compare the recovered product mass with its theoretical maximum.
Formula
Yield (%) = actual product mass / theoretical product mass × 100
Actual product mass: 80 g · Theoretical product mass: 100 g · Percent yield ≈ (80 g × 0.001 kg/g)÷(100 g × 0.001 kg/g)×100
How to use
- Enter the recovered product mass.
- Enter the theoretical mass of the same product.
- Read percent yield and check any value above 100%.
Examples
- 3 g recovered from a theoretical 4 g gives 75%.
Frequently asked questions
What is theoretical yield?
The maximum predicted by the balanced equation and limiting reactant.
Can the result exceed 100%?
The arithmetic can. Check residual solvent, impurities, measurement errors and the theoretical mass.
Can theoretical mass be zero?
No. Percent yield is undefined when the denominator is zero.
