The extinction coefficient for FD&C Blue Dye #1 is 138,500 cm-L/mol at 630 nm. A chemist collected the following data at 630 nm. She also found that the absorbance of an FD&C Blue Dye #1 solution of unknown concentration was 0.295. Use your graphing calculator to generate a standard curve from this data set, and use it to determine the concentration of the unknown solution. Express the answer in micromolar (notice micro means 10-6)

Concentration
of Blue Dye (M)		 Absorbance
@ 630 nm
7.58x10-6 0.101
3.26x10-5 0.288
5.17x10-5 0.521
8.63x10-5 0.782
