I understand you use Avogadro's constant to solve part b, but isn't the constant usually used to find atoms per mol? not photons per mol?

Avogadro's constant can be used to find the moles of anything really. Yes, you can use it to find the quantity of atoms, but you can also apply it for molecules, formula units, photons, etc.

1 mol of photons is 6.022 x 10^23 photons. The definition of the mole is that it contains as many objects(not necessarily atoms) as there are atoms in 12g of carbon-12.

Yup, Avogadro's number is really just a number- it can be used to mean 6.022 x 10^23 units of anything
