Calculate the value of mean free path ( $\displaystyle \lambda$ ) for oxygen molecules at temperature $\displaystyle 27^{\circ} \mathrm{C}$ and pressure $\displaystyle 1.01 \times 10^5 \mathrm{~Pa}$. Assume the molecular diameter $\displaystyle 0.3$ nm and the gas is ideal. $\displaystyle \left(\mathrm{k}=1.38 \times 10^{-23} \mathrm{JK}^{-1}\right)$
