We have energy E = hc/λ, where h is Planck's constant c is speed of light and λ is the wavelength.

So Energy , [tex]E=\frac{6.63*10^{-34}*3*10^8}{532*10^{-9}} =3.73*10^{-19}J[/tex]

Energy of one mol = [tex]3.73*10^{-19}*6.023*10^{23}=225 kJ/mol[/tex]

Energy of one mol of photons generated from this device = 225 kJ
