Estimate the mean free path for a water molecule in water vapour at 373 K.

What is mean free path for oxygen molecule at room temperature (300K)and at atmospheric pressure of 1atm? (given diameter of oxygen molecule is 2.9times10^(-10)m)

Calculate the mean free path of gas molecules, if number of molecules per cm^(3) is 3 xx 10^(19) and diameter of each "molecule" is 2Å .

The mean free path of molecules of a gas ,(radius r0 is inverselty propotional to:
