1.B.7 part B

[Lauren_Hayashi_1E]

Hi, I was wondering for part B of this problem, it says you are using the same wavelength, so would this mean you would assume that the energy is also the same? Or would it usually be given? I was just confused on how the solution automatically applied it by multiplying the answer by 3.37x10^-19 J.

Yes, this assumes that the energy is the same as in part A. The only part of the question that changes is that there's 5 mg of sodium instead of one atom.

So to clarify for this question, would the correct steps be to find the energy of the light with the given wavelength and then the multiply the number of moles of the substance by Avogadro's number and also by the energy of light?
