Chemistry

Before working this pre-lab exercise read the theory,experimental precedures and sample calculations outlined in thelaboratory manual. Suppose that a student collects the followingspectrophotometric data to determine the relative concentrations ofHMR and MR in solution: The abosorbance at 425 nm was measured tobe 0.310 and at 520 nm was 0.770, the slopes corresponding tostandard Beer's Law plots were as follows: Î±IA = 0.072 Î±IB = 0.306Î±IIA = 0.760 Î±IIB = 0.036 Using this data, calculate the ratiobetween the relative concentrations of MR- and HMR in thissolution.
