What is the energy in Joules of a mole of photons of microwave light having a frequency typical of microwave? (frequency = 3.0 x 10^9 Hz)
I tried using the equation E= h x frequency, but I ended up with the answer 1.98 x 10^-24 instead of the correct answer 1.2 J, so there must be another step that I'm missing.
Thanks for showing your work. It made it quick to know what was wrong. You found the energy per photon. For a mole of photons multiply by 6.02E23.
