34 grams NH3 = _____ moles?

34 grams of NH3 (the three is subscript) = ___ moles.

I think the answer is two-
34 grams/1 x 1 mole/17 (the atomic mass or molar mass) = 34/17 = 2

Is this right?
If not, can you try and explain where I went wrong?
THANKS

Yes. You might show that the mass of nitrogen is 14, hydrogen one, to show where 17 came from.

Yes, you did it right. The total grams of the molecule is only half of the given grams; so, 2mols.
