Chemistry

Chemical Reaction Yield Calculator

Compute the theoretical yield (in grams) of a chemical reaction from the limiting reactant’s mass, the reactant and product molar masses, and the stoichiometric ratio. The first step in evaluating reaction efficiency — compare against your actual experimental yield to get percent yield.
