For a 3D free electron gas, derive expressions for the Fermi momentum, Fermi energy, and density of levels. Then plot the density of levels and contrast its behavior as a function of energy. Your answers should be expressed in terms of the electron concentration n = N / V and some combination of fundamental constants.
