Reaction of sodium carbonate reacted with ethanoic acid is,
 
NaHCO subscript 3 space plus space straight C subscript 2 straight H subscript 4 straight O subscript 2 space space space rightwards arrow with space space space space space on top space space NaC subscript 2 straight H subscript 3 straight O subscript 2 space plus space straight H subscript 2 straight O space plus CO subscript 2
 
Mass of sodium carbonate = 5.3 gm
 
Mass of ethanoic acid = 6 gm
 
Mass of Sodium ethanoate = 8.2 gm
 
Mass of carbon dioxide = 2.2 gm
 
Mass of water = 0.9 gm
 
Total mass of reactant = (5.3 + 6)
                                 =11.3 gm
 
Total mass of products =( 8.2+2.2+0.9 )
                                  = 11.3 gm
 
Total mass reactant = Total mass of products.
 
Therefore the observations are in agreement with law of conservation of mass.
