While cleaning the organic stockroom,a student found a bottle of ethanol labeled "Denatured with Benzene." He decided to determine the concentration of benzene in the ethanol by acquiring the UV spectrum of the liquid in a 2.0 cm cell.The spectrum exhibited an absorption band at 260 nm which was attributable to benzene,and the absorbance of this band was 0.69.In a reference source,the student found that the molar absorptivity of this benzene band in ethanol was 230 M^-1cm^-1.Show how the student calculated the concentration of the benzene in the ethanol.
