An orange colored solution is prepared by mixing a red dye solution with a yellow dye solution and the absorbance was measured at the analytical wavelengths of 430 nm and 500 nm. The following table provides the molar absorptivity for the red and yellow dye at each analytical wavelength. Wavelength, λ (nm) Part: 0/2 Part 1 of 2 500 430 (Red, µM 1¹) -1 cm 0.0279 0.00506 X & (Yellow, μM ¹) -1 cm 0.000549 0.0167 S Absorbance Calculate the concentration (in µM) of the yellow dye in the mixture. Be sure your answer has the correct number of significant digits. [yellow] = μM 0.405 0.474
