Theoretical Yield Calculator
Compute theoretical yield (g) from moles of limiting reactant, stoichiometric ratio, and product molar mass.
Result
Theoretical yield
29.220 g
0.5000 mol of product.
- Moles limiting × ratio0.5 × 1 = 0.5000 mol product
- Product molar mass58.44 g/mol
- Theoretical yield (g)29.2200
Step-by-step
- Moles product = moles limiting × ratio = 0.5 × 1 = 0.5000.
- Grams = moles × molar mass = 0.5000 × 58.44 = 29.220.
How to use this calculator
- Find the limiting reactant (use the limiting-reactant calculator).
- Plug in moles, ratio, and product molar mass.
- Read theoretical grams.
About this calculator
Theoretical yield is the maximum product you could get if the reaction went to completion with no losses. Find the limiting reactant first (the one that runs out first), apply the stoichiometric ratio from the balanced equation, then convert moles → grams via molar mass.
Frequently asked
From the balanced equation. e.g., 2 H₂ + O₂ → 2 H₂O, so the H₂O:H₂ ratio is 2:2 = 1:1.
