When 4.2 g `NaHCO_(3)` is added to a solution of `CH_(3)COOH` weighing 10.0 g, it is observed that 2.2 g `CO_(2)` is released into atmosphere . The residue is found is weigh 12.0 g . Show that these observations are in argreement with the law of conservation of mass.

Text Solution

Verified by Experts

`NaHCO_(3) + CH_(3)COOH to CH_(3)COONa + H_(2)O + CO_(2)`
Initial mass =4.2 + 10=14.2
Final mass=12+2.2=14.2
Thus, during the course of reaction law of conservation of mass is obeyed
