### Part B on HW 1.25

I calculated parts a and c, however, I am having trouble with what I am suppose to do with the 5.00mg of sodium atoms.
The question is: "Sodium vapor lamps, used for public lighting, emit yellow wavelength 589nm. How much energy is emitted by:
b) 5.00mg of sodium atoms emitting light at this wavelength

First, convert 5.00 mg to moles. After that, multiply the moles with Avogadro's constant and the energy value you calculated from part a.
