The number of atoms in 8 moles of O2 is:
n(O2) = 8 moles
N = n(O2) 2 (since there are 2 atoms of oxygen in 1 molecule of O2)
N = 8 2
N = 16 atoms

Therefore, there are 16 atoms in 8 moles of O2.

The number of molecules in 710^23 molecules of P is:
N(P) = 710^23 molecules
n = N(P) / 1 (since there is 1 molecule of P in each molecule of P)
n = 7*10^23 molecules

Therefore, there are 710^23 molecules in 710^23 molecules of P.
