Suppose you measure the absorbance of a yellow dye solution in a 1.00 cm cuvette (b=1.00 cm).The absorbance of the solution at 427 nm is 0.44 . If the molar absorptivity of yellow dye at 427 nm is 27400 M–1cm–1, what is the concentration of the solution in M?

Examine the given Beer's law standard curve for an unknown dye measured in a 1.0 cm cuvette.What is the concentration (in M) of a sample of the unknown dye with an absorbance of 0.23 at 542 nm?

Assume the concentration of food coloring is doubled in a solution, explain how each of the following would change.a. Absorbance of solution.

A solution was prepared by dissolving 118.9 mg of K2Cr2O7 in 1.000 L of water. A 10.00 mL aliquot was transferred to a 100.0 mL volumetric flask and diluted to the mark. The dilute solution had an absorbance of 0.206 at 400 nm, in a 1.00 cm cell. a. What is the concentration of the dilute solution in ppm? b. Using Beer’s Law equation, calculate the molar absorptivity of K2Cr2O7
