Cоnsider а UV-VIS аbsоrptiоn spectrometer with no cаpability to subtract blank signals automatically. An organic compound (A) was dissolved in ethanol and the absorbance of the standard solution (0.266 a. u.) was measured at its maximum absorption wavelength (278 nm) a 1cm quartz cuvette. If the absorbance signal of ethanol at 278nm was 0.08 a. u., and the standard concentration was 25 mg/mL, what is the absorptivity of A at its maximum absorption wavelength? a) 7.44 L/mol.cm b) 7.44 x 10-3 L/cm.g c) 7.44 L/cm.g d) 7.44 x 10-3 L/mol.cm e) None of the answers.
