The volume of the copper piece is V = 1.28 cm^3. Estimate the number of states the electrons between energies 0.981*E to E. Fermi energy of copper is E = 7.0 eV. Assume that the density of states is constant over the energy gap and use the value of the density of states at the center of the gap. The volume of the copper piece is V = 1.28 cm^3.
