Determine energy flux density and quantum number of electron, Science

a. A point source of 60Co emits equal numbers of photons of 1.17 and 1.33 MeV giving a flux density (i.e. fluence rate) of 5.7 * 109 photon cm-2 s-1 at a specified location. What is the energy flux density (i.e. energy fluence rate) expressed in MeV cm-2 s-1?

b. Give the quantum numbers of all electrons in a silicon (Z=14) atom.
