Theoretical Yield Calculator

Calculate the theoretical yield of a product from reactant mass and stoichiometry.

The Theoretical Yield Calculator predicts the maximum amount of product a chemical reaction can produce based on stoichiometry. It uses the mass of the limiting reactant, molar masses, and the mole ratio from the balanced equation.

Enter the mass of your reactant, its molar mass, the molar mass of the desired product, and the mole ratio (product moles per reactant mole from the balanced equation). The calculator converts to moles, applies the ratio, and converts back to grams.

Theoretical yield represents the ideal maximum output assuming 100% conversion with no losses. It serves as the benchmark against which actual yield is compared to calculate percent yield.

Frequently Asked Questions

What is theoretical yield?
Theoretical yield is the maximum amount of product that could be formed from a given amount of reactant, assuming complete conversion with no losses.
What is a mole ratio?
The mole ratio comes from the coefficients of the balanced chemical equation. For 2H2 + O2 -> 2H2O, the ratio of H2O to O2 is 2:1.
What is the limiting reactant?
The limiting reactant is the reactant that runs out first and determines the maximum amount of product formed. Use its mass for this calculation.
