Student measured the absorbance of the substance x depending on its concentration in solution. she used 0.2 cm cuvette. her calibration curve is a straight line with the slope 2.3-103 m1. the extinction coefficient of substance x in this solution is: 4.6-10-2 m-1.cm not enough data to determine the extinction coefficient: wavelength is required o1.2.104 m: 1. cm1 o2.3-103 m: 1 not enough data to determine the extinction coefficient: concentration is required
