An unspecified ratio of nitrogen gas and hydrogen gas are mixed in a container and then react to form ammonia. the initial mole fraction of nitrogen gas and the final mole fraction of nitrogen gas are the same. (nitrogen is not completely consumed in this reaction.) what was the initial mole fraction of hydrogen gas?
