The density of sodium is 0.971 g/cm3 and it has an atomic weightof 22.9897 g/mol. Each sodium atom contributes one valence electronto the metal, so the number of electrons per unit volume, N/V, isequal to the number of sodium atoms per unit volume.
  a) Calculate the number density of atoms per unitvolume, N/V.   b) Calculate the Fermi energy ofsodium.   c) Calculate the Fermitemperature.  d) At room temperature (298 K), calculatethe chemical potential.  e) Calculate the degeneracypressure for the electron gas.
