Presume that we have a mixture of N2 (g) and O2 (g) of unknown composition whose total pressure is 385torr. If all the oxygen as is distant from the mixture by reaction with phosphorus, which doesn't react directly with nitrogen, subsequently the new pressure is 251torr.
Compute
(a) the partial pressure of nitrogen and
(b) the mole fraction of each gas in the original mixture.
