1B.7 HW prob
for parts b and c where do you find out that to convert the atoms to joules it's a multiplication of 3.37x10^-19? I can't find that conversion anywhere...

Re: 1B.7 HW prob
You should have gotten 3.37 x 10^-19 J as your answer for part a when calculating the energy of one sodium atom, which you then use to convert to grams and moles in parts b and c.
Re: 1B.7 HW prob
For this problem, you have to remember that one sodium atom generates one photon, so the energy you calculate in part a is the same as the energy emitted by one sodium atom when it generates a photon. Knowing this just use the conversion (answer to part a in Joules)/1atom Na to find the answers to part b and c.
Re: 1B.7 HW prob
For E=hv, this equation gives the energy of one photon. Every time you use this equation, the energy given is per photon.
