a) One possibility Rayleigh investigated was that "atmospheric nitrogen" was pure and "chemical nitrogen" contaminated with a lighter gas. Assume that "chemical nitrogen" was really a mixture of H2 and N2; compute the mole fraction of H2 needed to account for the difference with "atmopheric nitrogen." Now assume instead that "chemical nitrogen" was a mixture of atomic and molecular nitrogen; compute the mole fraction of atomic N that would account for the observed measurements.
b) With the hindsight of knowing accurate values for the molar masses of nitrogen and argon, compute the mole fraction of argon in "atmospheric nitrogen" on the assumption that it was a mixture of nitrogen and argon and "chemical nitrogen" was pure nitrogen.
