Theoretical yield calculator
Enter the limiting reactant you have already identified; other reactants must be sufficient.
Formula
n_product = n_limiting × b/a; mass (g) = n_product × M_product (g/mol)
Limiting reactant amount: 2 mol · Theoretical product amount ≈ (2 mol)×(2)÷(1) · Theoretical product mass ≈ (4)×(36.46)
How to use
- Enter the amount of the limiting reactant.
- Enter its coefficient a, product coefficient b and product molar mass.
- Read the theoretical product mass and amount.
Examples
- 2 mol Cl₂ with excess H₂ yields 4 mol HCl, or 145.84 g at 36.46 g/mol.
Frequently asked questions
Does it identify the limiting reactant?
No. Identify it from all available reactants before using this tool.
Which coefficients should I enter?
Use positive whole-number coefficients from the same balanced equation.
Will I obtain this much product?
This is the stoichiometric maximum; incomplete reaction and losses reduce actual yield.
