Theoretical Yield Calculator
Calculate the theoretical yield of a chemical reaction in grams or moles. Determine limiting reagents.
Theoretical yield is the maximum amount of product that can be generated from a given amount of reactant, assuming a perfect chemical reaction.
Calculator Inputs
From balanced equation (e.g. the "2" in 2A -> B)
To calculate percent yield

How It Works
Convert reactant mass to moles, apply the mole ratio from the balanced equation, and convert product moles back to grams.
Worked Examples
Reaction A -> B (1:1 ratio)
10g / 100g/mol= 0.1 mol0.1 mol * (1/1)= 0.1 mol0.1 mol * 150g/mol= 15gTips & Best Practices
- •Always start with a balanced chemical equation.
- •Find molar masses using the periodic table.
Frequently Asked Questions
What is percent yield?
Percent Yield = (Actual Yield / Theoretical Yield) * 100%. It measures efficiency.
