Question: question 2 a gaseous mixture of co co2 4 and...

Question details

Question 2 A gaseous mixture of CO, CO2, СН4, and N2 is analyzed with a gas chromatograph. The output appears on a strip-chart recorder, as shown here. A1 45.0 A2 25.0 A3 80.0 CO Area = A CO2 Area -A Area-A CH4 Area A Signal Time 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 (CH4) to nitrogen is 0.250. Physical Property Tables
What are the mole fractions of the four species in the gas? Xc02 = XCO =
Molecular Weight What is the average molecular weight of the gas? g/mol the tolerance is +/-2%
