======= ####21. The compressibility of a gas is less than unity at STP. Therefore,
3e0f7ab6f6a50373c3f2dbda6ca2533482a77bed (a) $V_{m}>22.4 \mathrm{~L}$
(b) $V_{m}<22.4 \mathrm{~L}$
(c) $V_{m}=22.4 \mathrm{~L}$
(d) $V_{m}=44.8 \mathrm{~L}$

Show Answer
Solution:
- Compressibility factor $(Z)=\frac{V}{V_{\text {id }}}<1$ (given)
$$ \begin{array}{lc} \Rightarrow & V<22.4 \mathrm{~L} \ \because & V_{\text {id }}(1 \mathrm{~mol})=22.4 \mathrm{~L} \text { at STP } \end{array} $$
