About Percent Yield and Theoretical Yield

Percent yield measures the efficiency of a chemical reaction by comparing the actual yield to the theoretical yield. Theoretical yield is the maximum amount of product that can be formed from given reactants, based on stoichiometry.

Key Formulas:

  • Percent Yield = (Actual Yield / Theoretical Yield) × 100%
  • Theoretical Yield (g) = (Mass Reactant / Molar Mass Reactant) × Stoich Ratio × Molar Mass Product

Units:

  • Grams (g)
  • Moles (mol)

Applications:

  • Evaluating reaction efficiency in labs
  • Optimizing industrial chemical processes
  • Identifying sources of product loss
