Pt (II) and TI (III) are two metals that can be determined by UV spectrophotometry with Metromeprazine (C19H24N2S2). The PtM complex has a max at 545 nm and the TIM complex at a max of 621 nm. To 25 ml of the sample with excess of reagent M, they were diluted to 50 ml with the appropriate solvent. Calculate the concentration of TI in the test sample with the following data. | E (M' cm³') 545 nm |ɛ (M' cm') 621 nm PtM TIM Absorbance b=1 cm 6.29 E4 1.15 E3 3.55 E2 5.64 E4 0.595 0.518 Notes Molecular weight of Pt= 195.078 g/mol Molecular weight of Ti = 47.90 g/mol The molecular weight of Metromeprazine= 344.14 g/mol О а. 1.250E-03м O b. 2.48E-04 M Ос. 1.80E-05 м O d. 7.124E-07 M Ое. 1.150E-0з м
