An electron in a hydrogen atom undergoes a transition from the n = 3 level to the n = 6 level. to accomplish this, energy, in the form of light, must be absorbed by the hydrogen atom. calculate the energy of the light (in kj/photon) associated with this transition.

What is the conversion factor between kg/m^3 and g/m^3. express your experimental values for the densities in kg/m^3.
