Mass of Product vs Mass of Reactant
公式
## 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.
计算示例
10 g of Ca (40.08 g/mol) reacting 1:1 to form CO2 (44.01 g/mol).
- 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
常见问题
What is stoichiometry?
The calculation of quantities of reactants and products in chemical reactions based on balanced equations.
Why must the equation be balanced?
Balancing ensures conservation of mass and gives correct mole ratios between substances.
What if I have multiple products?
Calculate each product separately using its own coefficient and molar mass.
