Chromatographic analysis showed that the mixture contai

Chromatographic analysis showed that the mixture contains toluene, styrene, and cumene with peak areas of 151, 219, and 91 mm2, respectively. Then standard mixtures were introduced with a concentration of toluene 2 mg / l, styrene and cumene 3 mg / l, and benzene 1 mg / l. The peaks obtained had areas of 63, 94, 88, and 37 mm2 for toluene, styrene, cumene, and benzene, respectively. Calculate the percentage of components in the sample. Take benzene as a standard.
