The Theoretical Yield Calculator is a powerful chemistry tool designed to calculate the maximum possible amount of product that can be formed from a given set of reactants. By entering the masses, molar masses, and stoichiometric coefficients of the reactants and product, this calculator automatically determines the limiting reagent and the theoretical yield in grams. It is an essential resource for students, teachers, and laboratory chemists who want to simplify stoichiometry calculations and improve accuracy in chemical experiments. Understanding theoretical yield helps predict product quantities, identify reaction efficiency, and compare actual yield to expected results. Use this free and easy-to-use tool to master your chemistry calculations with confidence.
