Theoretical Yield Calculator

Theoretical yield is the most product a balanced equation allows — the benchmark every real experiment is judged against. From the moles of limiting reactant, the mole ratio, and the product's molar mass, this tool predicts that ceiling.

How to interpret the result

Worked check: 2H₂ + O₂ → 2H₂O with 2.00 mol O₂ limiting gives 2.00 × (2/1) × 18.015 = 72.06 gram of water. Real yields always fall short — side reactions, incomplete conversion, and transfer losses.

Assumptions

The limiting reactant is correctly identified
The reaction proceeds to completion with no side products
