### ENERGY PER MOLE OF PHOTONS

When finding the energy PER MOLE of photons, why does it make sense to multiply by avogadro's number?

I would imagine since 1 mole= 6.022x10^23 "things"/atoms, and photons contain packets of energy aka packets of electrons (absorbed or emitted). I may be wrong but this is how I interpreted it?

I agree with Jade and think it definitely has to do with the idea that single photons interact with single electrons. I think multiplying by Avogadro's Number has to do with that 1-1 relationship.

The units of Avogadro's number is "things" per mole, which is why when the energy of a photon is given per mole, we have to multiply by Avogadro's number to determine energy per photon.
