The Fermi energy of a metal

A metal has an electron density of 7.0E+27 electrons per cubic meter. Calculate the Fermi energy at 0 K assuming that E = 0 is the bottom of the band.

EF = eV

The Fermi function is smeared out over a region of roughly 2kBT. What is 2kBT/EF for this metal at T = 300 K?

2kBT/EF =
