With (1) pV=nRT (n is given in moles)
and (2) pV=NkT (n is given in number of molecules)

it implies that nRT=NkT --> nR=Nk --> k=R*n/N

Given that k=R/N_a (N_a is the number of Avogadro, # molecules per mole)
this gives that N_a equals N/n

I think you got disoriented by the different kinds of n's.
