A protein’s concentration can be determined spectrophotometrically by mixing it with an indicator called a Bradford reagent and measuring the amount of light absorbed by the protein. Use the plot below to determine the mass of protein (in micrograms, μμg ) in 100.0 mL of the solution if its absorbance is 0.398. A. 52 B. 3.1 C. 2.4 D. 0.52 E. 0.031
a. When the light source is monochromatic, Beer's Law holds true. b. Beer's Law establishes a relationship between the concentration of a sample and its absorbance, wherein absorbance is the ratio of light leaving the sample to light entering it. c. For solutions that have more than one absorbing species, Beer's Law holds true even if the analytes of interest don't interact.
