Understanding Percent Yield

Percent yield measures the efficiency of a chemical reaction by comparing the actual amount of product obtained (actual yield) to the maximum amount that could be produced (theoretical yield). It's expressed as a percentage.

Formula

Percent Yield = (Actual Yield / Theoretical Yield) × 100%

Common Percent Yield Ranges

  • Excellent: > 90%
  • Very Good: 80-90%
  • Good: 70-80%
  • Fair: 50-70%
  • Poor: < 50%
