# In a reaction, 5.3g 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 acetate. Show that these observations are in agreement with the law of conservation of mass. Sodium carbonate + acetic acid $$\rightarrow$$ Sodium acetate + carbon dioxide + water

Sodium carbonate + Acetic acid $$\rightarrow$$ Sodium acetate + Carbon dioxide + Water

(5.3g) + (6g) $$\rightarrow$$ (8.2g) + (2.2g) + (0.9g)

$$\Rightarrow$$ 11g = 11g

$$\Rightarrow$$ LHS = RHS

$$\therefore$$ Mass of reactant = Mass of product

which satisfies the law of conservation of mass.
