The discovery of the element argon by Lord Rayleigh and SirWilliam Ramsay had its origins in Rayleigh’s measurements of thedensity of nitrogen with an eye toward accurate determination ofits molar mass. Rayleigh prepared some samples of nitrogen bychemical reaction of nitrogen-containing compounds; under hisstandard conditions, a glass globe filled with this ‘chemicalnitrogen’ had a mass of 2.2990 g. He prepared other samples byremoving oxygen, carbon dioxide, and water vapour from atmosphericair; under the same conditions, this ‘atmospheric nitrogen’ had amass of 2.3102 g (Lord Rayleigh, Royal Institution Proceedings 14,524 (1895)). With the hindsight of knowing accurate values for themolar masses of nitrogen and argon, compute the mole fraction ofargon in the latter sample on the assumption that the former waspure nitrogen and the latter a mixture of nitrogen and argon.Please show work.
