Question
the atomic spectrum of lithium has a strong red line at 670.8 nm. what is the energy of each photon of this wave length? What is the energy of 1 mole of these photons??
-do you use the e=h x v ??
-do you use the e=h x v ??

yes, but they give you the wavelength
e = h c / λ
make sure your units are consistent
e = h c / λ
make sure your units are consistent
