For a free electron gas in two dimensions, derive the relation between the number density of electrons and the Fermi wave vector.

In condensed matter physics, the free electron gas in two dimensions is a model that describes the behavior of non-interacting electrons in a 2D system. The relation between the number density of electrons and the Fermi wave vector can be derived as follows:
