For each of the three species, the area under the peak is approximately proportional to the
number of moles of the indicated substance in the sample. From other information, it is
known that the molar ratio of methane (CH:) to nitrogen is 0.200.
(a) What are the mole fractions of the four species in the gas?
(b) What is the average molecular weight of the gas?
