Question 2 (1 point) Saved 7 A sample containing 2.7 x 10-4 M green fluorescent protein shows an absorbance of 0.187 at 509 nm. Calculate its molar absorptivity constant (e). Your Answer: 1 Answer units Remember Beer's Law is Abs = b c. The path length of the sample is always 1 cm, the diameter of the cuvette. Make sure you also distinguish the absorbance reading from the wavelength at which the reading is taken. Beer's law refers to the reading of absorbance units.
