JEE Main 2025 — Redox Reactions Question with Solution

Some ${\mathrm{CO}}_2$ gas was kept in a sealed container at a pressure of 1 atm and at 273 K . This entire amount of ${\mathrm{CO}}_2$ gas was later passed through an aqueous solution of $\mathrm{Ca}(\mathrm{OH}{)}_2$. The excess unreacted $\mathrm{Ca}(\mathrm{OH}{)}_2$ was later neutralized with 0.1 M of 40 mL HCl . If the volume of the sealed container of ${\mathrm{CO}}_2$ was $x$, then $x$ is ____________ ${\mathrm{cm}}^3$ (nearest integer). [Given : The entire amount of ${\mathrm{CO}}_2(\mathrm{g})$ reacted with exactly half the initial amount of $\mathrm{Ca}(\mathrm{OH}{)}_2$ present in the aqueous solution.]
