The ionization energy of a certain element is 472 kJ/mol. However, when the atoms of this element are in the first excited state, the ionization energy is only 166 kJ/mol.
Based on this information, calculate the wavelength of light emitted in a transition from the first excited state to the ground state.

The energy should be 473-166 kJ/mol. I would then convert that to J/atom (use Avogadro's number), then E = hc/wavelength. Solve for wavelength. Check my thinking.
