The absorbance of a protein solution measured in a 1.0 cm cuvette at 278 nm was 1.145. The protein content of that solution, calculated from quantitative amino acid analysis, was 256 micrograms/mL. Calculate the extinction coefficient of the protein in unitsbof mL/mg/cm. Assume that the molecular mass of the protein was 13,000. Calculate the molar extinction coefficient.
