Calculate the energy in joules per photon of red light having a wavelength 655 nm. What is the energy of 1 mol of these photons?

  • chemistry - ,

    E = hc/wavelength. This gives you the energy of 1 photon (in joules). For a mole, multiply by 6.022E23. Don't forget that the wavelength must be in meters.
