How many atoms are there in five moles of water?

The conversion factor for moles to atoms is 1 mole = 6.022X10^23 atoms. However, water is a molecule, and as you can tell from the chemical formula, H2O (2 hydrogen and 1 oxygen) we can tell that there are 3 atoms. So, in order to accurately get the number of atoms you need to multiply 6.022X10^23 by 3 to get how many atoms are in 1 mole of water. You then must take your answer of 1.8066X10^24 and multiply it by 5. The answer should be 9.033X10^24 atoms are in 5 moles of water. Hope this helps!  

The answer is letter c
