The compressibility of a gas is less than unity at STP, therefore

The compressibility of a gas is less than unity at STP, therefore

Options

A $V_m\gt22.4 \mathrm{~L}$
B $V_m \lt 22.4 \mathrm{~L}$
C $V_m=22.4 \mathrm{~L}$
D $V_m=44.8 \mathrm{~L}$

Correct answer

B. $V_m \lt 22.4 \mathrm{~L}$

Step-by-step solution

Since, compressibility

(Z)=\frac{p V}{n R T}

for

Z

less than unity

\frac{p V}{n R T} \lt 1

or,

p V \lt n R T

[At STP,

p=1

\operatorname{atm}, T=273 \mathrm{~K}, R=0.0821 \mathrm{~L} \mathrm{~atm} \mathrm{~K}^{-1}

] i.e.

V \lt 1 \times 0.0821 \times 273

Thus,

V \lt 22.4 \mathrm{~L}
