The observed value of (gamma), see equation (8.3.6), for sodium is (4.3 times 10^{-4} mathrm{cal} mathrm{mole}^{-1} mathrm{~K}^{-2}).

Question:

The observed value of $\gamma$, see equation (8.3.6), for sodium is $4.3 \times 10^{-4} \mathrm{cal} \mathrm{mole}^{-1} \mathrm{~K}^{-2}$. Evaluate the Fermi energy $\varepsilon_{F}$ and the number density $n$ of the conduction electrons in the sodium metal. Compare the latter result with the number density of atoms (given that, for sodium, $ho=0.954 \mathrm{~g} \mathrm{~cm}^{-3}$ and $M=23$ ). image text in transcribed
