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

Consider a gas having a molar mass of 55 g/mol. At 496 K, what is the average speed of the gas molecules in m/s?

Note: Be very careful with units here. In the average speed equation, the mass is in units of kg/molecule.
