Chapter 5, Problem 116E

Consider the following reaction:

$4{\text{NH}}_3\left(g\right)\to 4\text{NO}\left(g\right)+6{\text{H}}_{\text{2}}\text{O}\left(g\right)$

If a container were to have 10 molecules of O₂ and 10 molecules of NH₃ initially, how many total molecules (reactants plus products) would be present in the container after this reaction goes to completion?
