Anyone know how to do this?
The answer is 6.0 x 10^23

You may need to re-read your notes on mole calculations, specifically check the part on Avogadro's constant. If there's something in your notes you're unsure about, let us know and we should be able to clarify for you

On the assumption you haven't learned about significant figures yet, that looks just fine!
