Interpretation Introduction

(a)

Interpretation:

Estimate the mole fractions of the four species in the gas.

Concept introduction:

It is given that a mixture of CO, CO2 , CH4 and N2 is analyzed using a gas chromatograph. The output graph has three species. In addition,

The area under the peak is approximately proportional to the number of moles.

The mole ratio of methane to nitrogen is 0.200.

Interpretation Introduction

(b)

Interpretation:

Calculate the average molecular weight of the gas.

Concept introduction:

It is given that a mixture of CO, CO2 , CH4 and N2 is analyzed using a gas chromatograph. The output graph has three species. In addition,

The area under the peak is approximately proportional to the number of moles.

The mole ratio of methane to nitrogen is 0.200.

Average molecular weight = Summation of the (mole fraction of the specie × molecular weight of the specie)
