In a reaction, 5.3 g of sodium carbonate reacted with 6 g ethanoic acid. The products were 2.2 g of carbon dioxide, o.9 g of water and 8.2 g of sodium ethanoate. Show that these observations are in agreement with the law of conservation of mass.

The law of conservation of mass states that the mass of the reactants and the product during a chemical equation remains the same
which is mass of the reactants = mass of the product during a chemical reaction.



5.3 g             +      6 g              =   2.2         +0.9        +8.2
                             11.3 g         =   11.3 g

We find that the mass of reactants is 11.3 g and the mass of products is also 11.3 g. Since the mass of products is equal to the mass of reactants, the given data verify the law of conservation of mass.
