 P: 819 Dealing with these has reminded me why I hated chemistry. What is the relationship between the above 3? Given atomic weight of nitrogen and Avogadro's constant, can the number of moles be found?

You don't need Avogadro's constant there.
1 mole = Atomic mass of Nitrogen

You should never call that atomic weight. It's atomic mass.

Number of moles of what?

That's new. My physic assignment called that atomic weight which throws in further confusion.

1 mole = 1 atomic mass of Nitrogen?

 Quote by Borek Number of moles of what?
Nitrogen. Given Avogadro's constant and the atomic mass of Nitrogen being 28g/mol, is it possible to determine the number of moles?

Oh sorry it should be --> not =

1 mole of Nitrogen --> atomic mass of nitrogen.

So 1 mol --> 28
x -->28
Cross multiply. You get 1 mole again.
Didn't you study that?

1 mole of any element --> atomic mass of that element.

I leave all these to Borek. He knows better.
