Limiting Reagent and Theoretical Yield Calculator

Theoretical yield = (mass/MW) × (stoich_P/stoich_A) × MW_P.

Calculates theoretical yield and percentage yield from the limiting reagent. Enter the limiting reagent mass, its molecular weight, the stoichiometric ratio, and the product molecular weight.
