gas chromatographic analysis of a mixture of organic compounds gave the following peak areas: 2-hexene= 2.5 2-bromogexane=4.0 2-henanol=1.8, calculate the mole percent compostion of the mixture
To calculate the mole percent composition of the mixture, you need to use the peak areas obtained from the gas chromatographic analysis.
First, add up all the peak areas to get the total peak area:
Total peak area = peak area of 2-hexene + peak area of 2-bromohexane + peak area of 2-hexanol
Total peak area = 2.5 + 4.0 + 1.8 = 8.3
Next, calculate the mole percent composition of each component in the mixture.
Mole percent composition = (Peak area of each component / Total peak area) x 100
For 2-hexene:
Mole percent composition of 2-hexene = (2.5 / 8.3) x 100 = 30.12%
For 2-bromohexane:
Mole percent composition of 2-bromohexane = (4.0 / 8.3) x 100 = 48.19%
For 2-hexanol:
Mole percent composition of 2-hexanol = (1.8 / 8.3) x 100 = 21.69%
Therefore, the mole percent composition of the mixture is approximately:
2-hexene: 30.12%
2-bromohexane: 48.19%
2-hexanol: 21.69%
