A solution prepared by dissolving 25.8 mg of benzene (78.11 g/mol) in hexane (86.16 g/mol) and diluting to 250 mL had an absorption peak at 256 nm and an absorbance of 0.266 in a 1.000-cm cell. If a sample of hexane with benzene had an absorbance of 0.153 at 256 nm in a cuvette with 1.000-cm path length, find the concentration of benzene in molarity. 5.41*10-4M 7.59x10M O 6.69x109M O 1.51x10-4M
