Question

If the density of oxygen is 1.44 kg/m3 at a pressure of 105 N/m2 , find the root mean square velocity of oxygen molecules.

Answer 1

Given that,

Density of oxygen is 1.44 kg/m³

Pressure, P = 105 N/m²

To find,

The root mean square velocity of oxygen molecules.

Solution,

The rms velocity of a gas molecule in terms of density and pressure is given by :

$v=\sqrt{\dfrac{3P}{\rho}} \\\\v=\sqrt{\dfrac{3\times 105}{1.44}} \\\\v=14.79\ m/s$

So, the root mean square velocity of oxygen molecule is 14.79 m/s.
