If $$\mathrm{n}$$ is the number density and $$\mathrm{d}$$ is the diameter of the molecule, then the average distance covered by a molecule between two successive collisions (i.e. mean free path) is represented by :

$$\frac{1}{\sqrt{2} \mathrm{n} \pi \mathrm{d}^2}$$

$$\frac{1}{\sqrt{2} n^2 \pi^2 d^2}$$

$$\frac{1}{\sqrt{2 n \pi d^2}}$$

$$\sqrt{2} \mathrm{n} \pi \mathrm{d}^2$$
