Expert Answer
According to law of conservation of mass, mass is neither created nor destroyed.
Na2CO3 + CH3COOH 
CO2 + CH3COONa + H2O
CO2 + CH3COONa + H2O 53g 60g 22g 82g 9g
According to Law of Conservation of Mass , Mass of reactants = Mass of products
Mass of reactants = 53 + 60 = 113 gm
Mass of products = 22 + 82 + 9 = 113 gm
Therefore, this data in agreement with the law of conservation of mass.
