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. The student also found that the absorbance of an FD&C Blue Dye #1 solution of unknown concentration was 0.561. Use your Vernier Graphical Analysis to generate a standard curve from this data set, and use it to determine the concentration of the unknown solution.
