Gas chromatographic analysis of a mixture of organic compounds gave the following peak areas (sq cm): hexane = 2.7, heptane 1.6, hexanol = 1.8, toluene = 0.5

a. Calculate the mole percent composition of the mixture. Assume that the response of the detector (area per mole) is the same for each component.

b. Calculate the weight percent composition of the mixture using the same assumptions as in part a.

#### Solution Preview

a. Hexane: 2.7/(2.7+1.6+1.8+0.5)=40.9%
Heptane: 1.6/(2.7+1.6+1.8+0.5)=24.2%
Hexanol: ...
