We´re asked to determine the energy (in kJ) of 3.00 moles of photons and a wavelength of 675 nm.
Remember that the Energy and the frequency of a photon are related by the following equation:
E is the energy of the photon (in J)
h is the Planck’s constant (h = 6.626x10-34 J*s)
ν is the frequency of the photon (in s-1)
How much energy (in kJ) do 3.00 moles of photons, all with a wavelength of 675 nm, contain?
A) 532 kJ
B) 177 kJ
C) 238 kJ
D) 418 kJ
E) 354 kJ
