Radiation in the ultraviolet region of the electromagnetic spectrum is quite energetic. It is this radiation that causes dyes to fade and your skin to develop a sunburn. If you are bombarded with 1.00 mol of photons with a wavelength of 288 nm, what amount of energy, in kilojoules per mole of photons, are you being subjected to?
E = hc/wavelength.
Convert 288 nm to meters for wavelength.
The first equation is per photon; therefore, multiply the answer obtained by 6.022E23 for a mole, then change to kJ.
