Answer & Solution

Correct Answer

(B) 224

Step-by-step Solution

Detailed explanation

\(\mathrm{Na}_{2} \mathrm{CO}_{3}+2 \mathrm{HCl}\) (dil.) \(\longrightarrow 2 \mathrm{NaCl}+\mathrm{CO}_{2}+\mathrm{H}_{2} \mathrm{O}\) \(1 \mathrm{~mol} \quad\) (dil.) \(1 \mathrm{~mol}\) \(=1.06 \mathrm{~g} \quad=22400 \mathrm{~cm}^{3}\)…
