Goal: Use the Open Colorimeter to experimentally calculate the molar extinction coefficient of FD&C Blue #1 Beer’s Law states that absorbance of a sample (Abs) depends on the molar concentration (c), light path length in centimeters (l), and molar extinction coefficient (ε) for the dissolved substance at the
