The molar absorptivity, ε, for the dye called xylenol blue (C23H22O5S, molar mass = 410.49 g mol-1) was found by experiment to be 8.15×103 L mol-1 cm-1 at 424 nm. The percent transmittance of a 960 mL solution of xylenol blue was determined to be 30.9%. If the path length of the cell is 2.19 cm, determine the mass (in g) of xylenol blue present in the solution. Report your answer to 3 significant figures in scientific notation.

Assuming a molar absorptivity of 50,000 (Liters/mol cm) calculate what molarity you would need to get an absorbance of 1.0, using Beers Law. A =ε c l, where A is the absorbance; ε is the molar absorptivity in L/mol cm; c is the concentration in mol/liter; and l is the path length in cm, which, in our case, is 1.00 cm. Algebraically rearranging gives c = A/ε l =A/ε. B) Start with 20 mg of your dye. Calculate what morality...

By Beer’s Law, determine the molar absorptivity of the iron (II) phenanthroline complex using maximum absorbance, the molar concentration of the standard iron solution, and the cell path length. I'm confused because on this lab we have calculated the max Wavelenth (497nm) and used a spectroscopy instrument to measue the max Absorbance at that wavelength for the other samples and unknown. Beers law seem simple, But how would I use it to find the molar absorptivity? SAMPLE (in ppm) Max...
