My son has a question and I am trying to help him. He is given the following:

2NH₃ + 3CuO  N₂ + 3Cu + 3H₂O

We are told that 2.24dm cubed of Ammonia was allowed to react. Then we are asked how many moles of Nitrogen will be formed. What I cannot understand is whether it is how many moles of N atoms or N₂ molecules? He has figured out that the volume going in equates to one mole of Ammonia, so it seems that you should get 0.5 moles of N₂ since the reaction requires 2 Amonia for each N₂. Am I off base? My son thinks I am wrong.

Appreciate any help.

Moles of N₂.

But 2.24 dm³ is not 1 mole.
