Percentage loss in mass, when

{NaHCO}_3(\mathrm{~s})

is heated in open vessel

2 {NaHCO}_3(\mathrm{~s}) \rightarrow {Na}_2 \mathrm{CO}_3(\mathrm{~s})+{CO}_2(\mathrm{~g})+{H}_2 {O}(\mathrm{g})

View answer and explanation

Correct option: B

36.9 \%

Option B (36.9%) is correct because the percentage loss in mass is calculated based on the molar mass of the gases released (CO₂ and H₂O) relative to the molar mass of NaHCO₃.
