Amole of red photons of wavelength 725 nm has kj of energy.

According to the general rules and basic knowledge of physics, without any doubds I can say that a mole of red photons of wavelength 725 nm has  [D] 165 kj of energy. I converted  a wavelength into energy in that way : 
=

Because its reliable.   there is no pollution  the chances of a radiation leak is low
