Mass of Product vs Mass of Reactant

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.

Example Calculation

10 g of Ca (40.08 g/mol) reacting 1:1 to form CO2 (44.01 g/mol).

  1. 01Moles reactant = 10 / 40.08 = 0.2495 mol
  2. 02Moles product = 0.2495 × (1/1) = 0.2495 mol
  3. 03Mass product = 0.2495 × 44.01 = 10.98 g
