2.66 molecules of ammonia are produced
Explanation:
We have bellow the chemical reaction between nitrogen (N₂) and hydrogen (H₂) which produce ammonia (NH₃):
N₂ + 3 H₂ → 2 NH₃
From the chemical reaction we see that 1 molecule of nitrogen reacts with 3 molecules of hydrogen, so 4 molecules of nitrogen will react with 12 molecules of hydrogen but we only have 4 molecules of hydrogen available, so the limiting reactant will the hydrogen. Knowing this we devise the following reasoning:
if 3 molecules of hydrogen produces 2 molecules of ammonia
then 4 molecules of hydrogen produces X molecules of ammonia
X = (4 × 2) / 3 = 2.66 molecules of ammonia
However it does not make sense to produce half a molecule of something (you can not do this in the real world), the problem will make sense if you talk about the number of moles of each substance, because in 1 mole of substance you have 6.022 × 10²³ molecules.
You may find in the attached picture the drawing of the molecules.
