Diatomic Gas

Molecule, is a collection of two or more atoms together (which constitute the smallest observable unit) into a pure material. There are some ways to represent the structure of a molecule. Factor symbols represent atoms in Lewis structures, and dots represent electrons that accompany them. A pair of mutual electrons (covalent bond) may be represented by a single dash. The ball-and-stick model depicts the spatial structure of the atoms better.

Question

collision diameter of 395 pm, and the pressure inside the container is 471 nTorr
(nanotorrs), find the average number of collisions per second (i.e., the collision rate or
collision frequency of the gas).
