Calculate the value of n; in which an oxygen atom, confined to a cubical box 45 mm on each side will have the same energy as the lowest energy available to a hydrogen atom confined to a cubical box 25x10-10 on each side. Find the Energy and what is the oxygen density of states at the energy in eV-1, taking into account spin.
