Answer:
For instance look at N (Nitrogen), you will see the atomic mass is 14.00674 grams. So that means if you had 1 mole of nitrogen atoms, it would weight, 14.00674 grams. Now we have to get what fraction of a mole you have. To start, you need know that all a mole means is you have 6.022 x 1023 atoms of that type.
