f. The GC trace below was obtained after injecting a mixture of butyric acid and ethyl butyrate into a gas chromatograph. i. Which peak, A or B, corresponds to ethyl butyrate? Circle your answer. [2 pt] Peak A Peak B ii. The average peak area for 0.2L of a pure sample of butyric acid is 20 . The average peak area for 0.2L of a pure sample of ethyl butyrate is 24 . Peak A has an area 1.6 times that of peak B. Taking into account your answer in part i (above) and the differences in detector response for the two compounds, what is the composition of the mixture by weight? [ 3pts] Composition of the mixture = % butyric acid by weight and % ethyl butyrate by weight
