Xg of benzoic acid on reaction with aq $\mathrm{NaHCO}_3$ released $\mathrm{CO}_2$ that occupied 11.2 L volume at STP. X is _____ g.

Step-by-step solution

1 mole benzoic acid will release 1 mole $\mathrm{CO}_2$ 11.2 $\mathrm{L} \mathrm{CO}_2$ at STP is $\frac{1}{2} \mathrm{~mole}_{\mathrm{CO}}^2$ which will be released by reaction with $\frac{1}{2}$ mole benzoic acid $$\begin{aligned} \text{ Mass of benzoic acid } & =\frac{1}{2} \times 122 \\ & =61 \mathrm{gm}\end{aligned}$$
