First you need to determine the energy required to break "one molecule" of nitrogen. You know how much is required to break 6.022E23 molecules(1 mole), so divide that 945,000 J/6.022E23 to find for 1 molecule. Then apply the E = hc/wavelength and see if that doesn't give you the correct answer.
it did work, thanks!
