Ammonia, at stp, 1.5L of N2 reacts with 4.5L of H2, if N2 and H2 are consumed, what volume of NH3 at stp will be produced?

2 answers

N2 + 3H2 ==> 2NH3
When using equations will all gases, one may use L as if they were moles.
1.5L N2 will produce 1.5 x (2/1) = 3.0L NH3 and
4.5L H2 will produce 4.5 x (2/3) = 3.0 L NH3.
So the answers is that 3.0 L NH3 will be produced at STP.
