Sally obtains a standard calibration curve for their assigned food dye by plotting absorbance versus concentration (in M) of known solutions and finds the following slope and intercept: y = 1.926x + 0.008 Sally finds that her original Kool-aid sample is too concentrated, so they dilute it by transferring 2.00 mL of the original Kool-aid sample into a new container and diluting to a total volume of 39.00 mL. If the absorbance of the dilute Kool-aid sample at the appropriate wavelength for their assigned dye is 0.318, determine the concentration (in M) of the assigned food dye in the original Kool-aid sample. Report your answer with three places after the decimal.
