Understand the math behind the mass-to-mass stoichiometry calculator. Each variable explained with a worked example.
Formulas Used
Mass of Product
mass_product = (mass_reactant / mw_reactant) * (coeff_product / coeff_reactant) * mw_productMoles of Reactant
moles_reactant = mass_reactant / mw_reactantVariables
| Variable | Description | Default |
|---|---|---|
mass_reactant | Mass of Reactant(g) | 10 |
mw_reactant | Molar Mass of Reactant(g/mol) | 40.08 |
coeff_reactant | Coefficient of Reactant | 1 |
coeff_product | Coefficient of Product | 1 |
mw_product | Molar Mass of Product(g/mol) | 44.01 |
How It Works
Mass-to-Mass Stoichiometry
Formula
mass_product = (mass_reactant / Mw_reactant) × (coeff_product / coeff_reactant) × Mw_product
Steps: grams to moles, apply mole ratio, moles to grams.
Worked Example
10 g of Ca (40.08 g/mol) reacting 1:1 to form CO2 (44.01 g/mol).
mass_reactant = 10mw_reactant = 40.08coeff_reactant = 1coeff_product = 1mw_product = 44.01
- 01Moles reactant = 10 / 40.08 = 0.2495 mol
- 02Moles product = 0.2495 × (1/1) = 0.2495 mol
- 03Mass product = 0.2495 × 44.01 = 10.98 g
