States of Matter - Result Question 21
21. The compressibility of a gas is less than unity at STP. Therefore,
(a) $V _m>22.4 L$
(b) $V _m<22.4 L$
(c) $V _m=22.4 L$
(d) $V _m=44.8 L$
(2000, 1M)
Show Answer
Answer:
Correct Answer: 21. (b)
Solution:
Compressibility factor $(Z)=\dfrac{V}{V _{\text {id }}}<1$ (given)
$\Rightarrow \hspace{6mm}V<22.4 L $
$\because \hspace{5mm} V _{\text {id }}(1 mol)=22.4 L \text { at STP }$
