The total mass of reactants equals 5.3 g plus 6.0 g, which is 11.3 g. The total mass of products equals 2.2 g plus 0.9 g plus 8.2 g, which is 11.3 g. Since reactant mass equals product mass, the law of conservation of mass is verified.
5.3 g of sodium carbonate and 6.0 g of acetic acid react to produce 2.2 g of carbon dioxide, 0.9 g of water and 8.2 g of sodium acetate. Verify whether the law of conservation of mass is valid.

The total mass of the reactants is obtained by adding 5.3 g of sodium carbonate and 6.0 g of acetic acid, giving 11.3 g. The total mass of the products is found by adding 2.2 g of carbon dioxide, 0.9 g of water and 8.2 g of sodium acetate, also giving 11.3 g. Because the mass of reactants equals the mass of products, the reaction obeys the law of conservation of mass.
