I'm having difficulty with this chemistry problem:

One of the wavelengths of light emitted by excited calcium atoms is 393 nm.  Calculate the energy of the photons emitted by one mole of atoms, in kJ and in kcal.  (Remember that 1 cal=4.184 J and 6.022 x 10^23 atoms = 1 mol)

If someone could walk me through this, I would really appreciate it.  Thanks!
