Answer to Question #342405 in Molecular Physics | Thermodynamics for rox

Question

At 0.0°C and 1.00 atm, 1.00 mol of a gas occupies a volume of 0.0224 m³.

Estimate the average distance between the molecules.

Answer 1

$pV=\frac mM RT,\implies$

$m=\frac{MpV}{RT}=14.01~g.$

$\rho=\frac mV=0.625~\frac{kg}{m^3}.$
