Theoretical Yield Calculator Formula

Understand the math behind the theoretical yield calculator. Each variable explained with a worked example.

Formulas Used

Moles of Product

moles_product = moles_limiting * (coeff_product / coeff_limiting)

Theoretical Yield

theoretical_yield = moles_limiting * (coeff_product / coeff_limiting) * molar_mass_product

Variables

coeff_productCoefficient of Product1
molar_mass_productMolar Mass of Product(g/mol)44.01

How It Works

How to Calculate Theoretical Yield

Formula

Yield = (moles_limiting × coeff_product / coeff_limiting) × Mw_product

First find moles of product from the mole ratio, then convert to grams.

Worked Example

0.5 mol of C reacts (1:1 ratio) to produce CO2 (44.01 g/mol).

moles_limiting = 0.5coeff_limiting = 1coeff_product = 1molar_mass_product = 44.01
  1. 01Moles product = 0.5 × (1/1) = 0.5 mol
  2. 02Yield = 0.5 × 44.01 = 22.005 g
