Solid molecular hydrogen. For H₂ one finds from measurements on the gas that the Lennard-Jones parameters are & = 50×10-¹6 erg and o = 2.96 Å. Find the cohesive energy in kJ per mole of H2; do the calculation for an fcc structure. Treat each H₂ molecule as a sphere. The observed value of the cohesive energy is 0.751 kJ/mol., much less than we calculated, so that quantum corrections must be very important.
