In a reaction 5.3g of sodium carbonate reacted with 6g of ethanoic acid. The products where 2.2g of CO., 0.9g water and 8.2g of sodium ethanoate show that these observations are in agrrengment with the law of conservation of mass.

In the given reaction, sodium carbonate reacts with ethanoic acid to produce sodium ethonoate, carbon dioxide and water.
Sodium carbonate + Ethanoic acid `to`
Sodium ethanoate + carbondioxide and water.
Mass of sodium carbonate=5.3g
Mass of ethanoic acid 6g
Mass of sodium ethanoate -8.2g
Mass of carbondioxide=2.2g
Mass of water `=0.9g`
Now total mass before the reaction`=(5.3 =6) g = 11.3g`
And total mass after the reaction `=(8.2 +2.2 +0.9)g - 11.3g `.
`:.` Total mass before the reaction= Total mass after the reaction
Hence, the given observations are in agreement with the law of .conservation of mass.
