Given - Temperature : 300 K

Atmospheric pressure: 1 atm

Diameter of oxygen molecule : 2.9*10-¹⁰ metre

Find - Mean free path for oxygen molecule at given conditions.

Solution : Mean free path = k*T/(√2*π*d²*P)

Mean free path = 1.38*10-²³*300/(1.414*π*(2.9*10-¹⁰)²*1

Mean free path = 1.38*10-²³*300/(3.7*10-¹⁹)

Mean free path = 4.14*10-²¹/3.7*10-¹⁹

Mean free path = 0.011 metres

The mean free path for oxygen molecule at given conditions is 0.011 metres.
