Answer the following question:
  In a reaction 5.3 g of sodium carbonate reacted with 6 g of ethanoic acid. The products were 2.2 g of carbon dioxide, 0.9 g water and 8.2 g of sodium ethanoate. Show that these observations are in agreement with the law of conservation of mass carbonate.
 
Sodium carbonate ​+ Ethanoic acid → + Carbon dioxide + water

5.3 g + 6 g →

Therefore, LHS = RHS

11.3 g = 11.3 g

Mass of reactant = Mass of product

This shows that during a chemical reaction,  = Mass of product.
