In a reaction, 5.3 g of sodium carbonate reacted with 6 g of acetic acid. The products were 2.2 g of carbon dioxide, 0.9 g water and 8.2 g of sodium Q acetate. Show that these observations are in agreement with the law of conservation of mass. Sodium Carbonate + Acetic Acid → Sodium Acetate + Carbon Dioxide + Water



The law of conservation of mass states that, during a chemical reaction, the sum of the masses of the reactants and products remains unchanged .

Hence, for the given chemical reaction


Since the Sum of masses of reactants = Sum of Masses of products , law of conservation of mass is obeyed.
