Answer:
We can find the binding energy by using the formulae of energy.
Energy(E) = hc/λ.
Where, h is the plank constant, c is the speed of light and λ is the wavelength.
Then, E = 6.626*10^-34 * 3 * 10^8 / 240*10^-9.
On solving we get value of Energy as 0.082*10^-17.
Hence, binding energy per mole will be 6.023*10^23 * 0.082*10^-17.
Which is 497000 Joules or 497 KJ.
