SUMMARY
The mass percent of CaCO3 in the original mixture can be calculated using stoichiometry based on the decomposition reaction of calcium carbonate (CaCO3) into calcium oxide (CaO) and carbon dioxide (CO2). Given a mixture mass of 0.656 g and a remaining CaO mass of 0.485 g after heating, the calculation shows that 59.3% of the original mixture was CaCO3. The balanced reaction equation is essential for determining the relationship between the masses of the reactants and products.
