HO HC CH3 compound A With a flask of certified primary standard of pure compound A, the researcher carried out the absorbance measurement (U.V. at 298 nm) of 6 different concentrations, using methanol and a 10 mm quartz cuvette and obtained the following results: C(ug/mL) Absorbância 0,2962 0,3943 0,4924 0,5905 4 9. 0,6886 0,7867 Knowing that at 298nm the peak of highest intensity occurs in the U.V. indicate what kind of transition is this probably referring to? With the data in the table determines the molar extinction coefficient of compound A? The absorbance reading of the injectable showed a value of 0.4436, what is the real value of concentration of this injectable? The absorbance reading of the tablet showed a value of 0.4826, which is the real value of mass of the asset contained in the tablet knowing that it was dissolved completely in 100mL of methanol? 00
