Question:

(a) Show that the density of states at the Fermi energy is given by in which n is the number density of conduction electrons.

(b) Calculate N (EF) for copper, which is a monovalent metal with molar mass 63.54 g/mol and density 8.96 g/cm3,

(c) Verify your calculation with the curve of Figure recalling that EF = 7.0 eV forcopper.
