The composition of the mixture by weight is 60% for peak A and 40% for peak B.

Peaks in chromatography are the locations on a chromatogram where the compounds of interest have reached their maximum concentration. On the graph, it is usually represented by a peak or a sharp peak. The peak's area is proportional to the amount of compound in the mixture.

Based on the answer in part one, the area of peak A is 1.5 times that of peak B. To find the composition of the mixture by weight, we must divide the area of peak A by the area of both peaks combined.

Therefore, the composition of the mixture by weight is:

Peak A: (1.5/2.5) x 100 = 60%

Peak B: (1/2.5) x 100 = 40%
