Stoichiometry with Real-World Constraints

Predict actual product mass by accounting for reagent purity and expected reaction yields.

Reactant Mass (g)

Reactant MW (g/mol)

Reactant Purity (%)

Reactant Molar Ratio

Product Molar Ratio

Expected Rxn Yield (%)

Product MW (g/mol)

Expected Actual Mass of Product

0.00 g

Theoretical Max Mass: 0.00 g

Yield Corrections

Ideal stoichiometry assumes 100% pure reagents and perfect reactions. Real-world bench chemistry requires corrections for hygroscopic reagent degradation (purity) and side-reactions/equilibria (percentage yield).

Calculation Pipeline:
1. Pure Reactant Mass = Mass * (Purity / 100)
2. Moles of Reactant = Pure Mass / MW_Reactant
3. Moles of Product = Moles_Reactant * (Ratio_Product / Ratio_Reactant)
4. Theoretical Mass = Moles_Product * MW_Product
5. Expected Mass = Theoretical Mass * (Yield / 100)
