Under some conditions ammonia can break down into its component gases:
2 NH3 (g) → N2 (g) + 3 H2 (g)
A container starts out with 4.27 moles of ammonia. The ammonia breaks down completely and the resultant gas mixture of nitrogen and hydrogen has a total pressure of 167 kPa. What is the partial pressure of the hydrogen in the mixture of gases. (Assume there are no other gases present)
