Chapter 3, Problem 3.35P
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.

2) As an example of precision and accuracy of data, suppose the % carbon in a single compound has been
measured thrce separate times by 2 different students. The theoretical % carbon is 21.34%.
Student 1: trial 1:26.11%,
trial 2: 26.24%
trial 3: 25.92 %,
Avg - 26.09
Student 2: trial 1: 20.35%.
trial 2: 22.64 %
trial 3: 19.79 %.
Avg = 20.93
a) Which student had the more precise data and how can you tell?
b) Which student had the more accurate data and how can you tell?
3a) Calculate the % error of Student 1 data in problem 2 above. Show all work below. WATCH SIG FIGS
