For electromagnetic radiation with a wavelength of 576.3nm, what is the frequency of the radiation in s^-1? What is the energy in J of one photon of the radiation? What is the energy in kJ of one mole of photons of the radiation?(adsbygoogle = window.adsbygoogle || []).push({});

--------------------------

I think I have the answer.

For the frequency, I did nu=c/lamba

nu = 2.9979x10^8/(576.3)

nu = 520197.8136

= 5.202 x 10^5

For the energy in J, I did:

6.6256x10^-34 x 5.202x10^5 = 3.447 x 10^-28

For the last part, I figured out the mols but don't know where to go from there:

3.447x10^-28 x 6.022x10^23 = 0.0002076mols

ideas??? please!
