# Q 1.     In a reaction, 5.3 g 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 → sodium acetate + carbon dioxide + water

Given, the reaction

sodium carbonate + acetic acid → sodium acetate + carbon dioxide + water

5.3g                       6g                     8.2g                     2.2g               0.9g

Now,

Total Mass on the Left Hand Side = 5.3g + 6g = 11.3g

Total Mass on the Right Hand Side = 8.2g + 2.2g + 0.9g = 11.3g

As Mass on the LHS is equal to RHS, the observation is in agreement with the law of conservation of mass.
