Why can Avogadros Number be used for so many different types of applications (atoms, molecules, photons, etc.)? Can someone please clarify the concept and its use? Thanks in advance. :)

Because a lot of things are measured in moles.

It is the number of molecules (or atoms- in a pure substance) in 1 mole of a substance/compound. The units are: # of atoms or molecules per mole.

Avogadros Number is not a concept; it is just a flat number used for counting particles. Any time there is 6.022 x10^23 of something that is equal to one mole. It makes it easier to count small particles.

Avogadro's number is the ratio between one atomic mass unit and one gram. That is to say that there are avogadro's number atomic mass units in one gram. It is used to make benchtop chemistry calculations simpler. That's it. There is nothing special other than that.
