What forces hold molecule solids together

Question 8 Lithium is a solid phase of lithium still unknown to science. The only difference between it and ordinary lithium is that Lithium forms a crystal with an fcc unit cell and a lattice constant. Calculate the density of Lithium.

When the system is at equilibrium, it contains NO 2 at a pressure of 0.817 atm, and N 2 O 4 at a pressure of 0.0667 atm. The volume of the container is then reduced to half its original volume.
