Spectrophotometry and Beer’s Law Absorption of Light of Dyes in Beverages   A calibration curve for the orange dye in a soft drink was obtained by plotting absorbance against concentration (M) for a series of solutions of known concentration. The slope of the calibration curve was 226 L/mol and the intercept was -0.011. The absorbance of an unknown soft drink was found to be 0.333 under the same conditions as the calibration curve. Calculate the concentration of the orange dye in the soft drink.
