Q. The compressibility of a gas is less than unity as STP. Therefore,
A) $v_{m} > 22.4\$L
B) $v_{m} < 22.4\$L
C) $v_{m} = 11.2\$L
D) $v_{m} = 44.8\$L
Explanation
(b)
The compressibility factor
$Z = \frac{p \times 22.4}{RT} = 1$ (for ideal gas)
$Z = \frac{p \times Vm}{RT} < 1$
$\therefore\frac{22.4}{V_{m}} > 1$ or $V_{m} < 22.4$
