Question:

Dyes are used in coloration products, such as textiles, paper, leather, and foodstuffs, and are required by law to be in gasoline to indicate the presence of lead. To monitor environmental contamination, analytical methods must be developed to identify and quantify these dyes. In one study, thermospray high-performance liquid chromatography/mass spectrometry was used to characterize dyes in wastewater and gasoline. The next table gives the relative abundance (relative frequency of occurrence) of commercial Diazo Red dye components in gasoline. Describe the relative abundance of red dye compounds with a bar graph. Interpret the graph.

REDDYE Red Dye Compound H CH3 CH5 C3H7 C7H15 C8H17 CH19 C0H1 Others Relative Abundance .021 .210 .354 .072
