To completely convert 9. 0 moles of hydrogen gas (h2) to ammonia gas, 3.0 moles of nitrogen gas (n2) are required.
<h3>What are moles?</h3>The mole is a SI unit of measurement that is used to calculate the quantity of any substance.
<h3 />The given reaction is
By the stoichiometry rule of ratio hydrogen: nitrogen
3 : 1
The reacted moles of nitrogen is equals to H/3 moles of reacted hydrogen
So, moles of nitrogen
Thus, 3.0 moles of nitrogen gas (n2) are required.

Explanation:
At each reflecting surface (benzene and glass) there will be 180 degree phase change.
Now, for constructive interference the optical path in benzene is .
Formula to calculate thickness of a benzene thin film is as follows.
Optical path length through benzene () =
Hence, substituting the given values into the above formula as follows.
Optical path length through benzene =
d =
=
= (as 1 nm =
= 204.9 m
Thus, we can conclude that minimum thickness of benzene is 204.9 m.
