A 0.1000 g portion of furadonin was dissolved in diphenylformamide, an alcoholic solution of potassium hydroxide was added, and the volume was adjusted to 50 ml. 0.6 ml of the resulting solution was taken into a volumetric flask with a capacity of 100 ml, the volume was brought to the mark with water. The optical density of the prepared solution, measured at a wavelength of 360 nm, in a 0.5 cm cuvette is 0.450. Calculate the molar light absorption coefficient of furadonin (M=238.16 g/mol).
