What is the volume of $\mathrm{CO}_{2}$ liberated (in litres) $\mathrm{at}$ 1 atmosphere and $0^{\circ} \mathrm{C}$ when $10 \mathrm{~g}$ of $100 \%$ pure calcium carbonate is treated with excess dilute sulphuric acid? (Atomic mass $\mathrm{Ca}: 40, \mathrm{C}: 12, \mathrm{O}: 16)$
  1. $0.224$
  2. $2.24$
  3. $22.4$
  4. 224

Solution

$\mathrm{CaCO}_{3}+\mathrm{H}_{2} \mathrm{SO}_{4} ightarrow \mathrm{CaSO}_{4}+\mathrm{H}_{2} \mathrm{O}+\mathrm{CO}_{2}$
$\begin{array}{lll}1 \mathrm{~mol} & 100 \mathrm{~g} & 22.4 \text { litre } \\ 1 \mathrm{~mol} & 10 \mathrm{~g} & 2.24 \text { litre }\end{array}$ *
