What is the volume occupied by $2 \mathrm{~g}$ of helium gas at STP? (molar mass of helium gas $=4 \mathrm{~g} \mathrm{~mol}^{-1}$ )
- $5.6 \mathrm{dm}^3$
- $22.4 \mathrm{dm}^3$
- $11.2 \mathrm{dm}^3$
- $2.0 \mathrm{dm}^3$
Solution
Moles of $\mathrm{He}=\frac{2}{4}=0.5$
$\therefore$ Volume occupied at STP $=0.5 \times 22.4=11.2 \mathrm{dm}^3$
