How do i work this out? How many atoms of oxygen is there in 2.35 moles of sodium phosphate?

Can anyone describe what to do here?How do i work this out? How many atoms of oxygen is there in 2.35 moles of sodium phosphate?
2.35 moles Na3PO4 x (4 moles O / 1 mole Na3PO4) x (6.023 x 10^23 atoms O / 1 mole O) = 5.66 x 10^24 atoms O.
