Saying that you have 2.0 moles of He is like saying that you have 2 dozen of something. We all know a dozen to be equal to 12, and in this case, the "dozen" is Avogadro's number (6.022*1023). If you multiply 2 dozen by 12, you'll have the number of whatever you're counting (24), and if you multiply 2.0 moles of He by Avogadro's number, you'll have the number of He atoms you're talking about.

How many atoms and are there in 36g of water?
1 mole of water is 18g. 36g of water is thereforeequivalent to 2 moles. 2 moles of water contains 4 moles of hydrogen and 2 moles of oxygen and so there are6 moles of atoms in 2 moles of water. 6 moles of atoms x (3.6x10^24) = 36.1x10^24 atoms
