Dinitrogen monoxide (N₂O; nitrous oxide) is a greenhousegas that enters the atmosphere principally from natural fertilize rbreakdown. Some studies have shown that the isotope ratios of ¹⁵N to ¹⁴N and of ¹⁸O to ¹⁶O in N₂O depend on the source, which can thus be determined by measuring the relative abundance ofmolecular masses in a sample of N₂O.(a) What different molecular masses are possible for N₂O?(b) The percent abundance of ¹⁴N is 99.6%, and that of ¹⁶O is 99.8%. Which molecular mass of N₂O is least common, andwhich is most common?
