Chapter 11, Problem 11A.4AE
Interpretation Introduction

Interpretation:

The molar concentration of the solute that has molar absorption coefficient 386 dm3mol1 cm1 at 540nm has to be calculated.

Concept introduction:

The Beer-Lambert law states that the intensity of light absorbed by a solution is directly proportional to the concentration of the solution and the path length of that the light has to travel in the solution.  The mathematical expression for Beer-Lambert law is given below.

Please help me with #2b & #3 using the data.
Heparin is used as an anti-coagulant. A risk of heparin use is thrombocytopenia, or low platelet count. This risk is minimized with the use of low molecular weight heparins (LMWH), therefore it is desirable to separate LMWH from higher molecular weight heparins. The method of choice to do this is molecular exclusion chromatography. Below is a chromatogram from a molecular exclusion chromatographic run. Peaks ranging from A to J are clearly distinguishable. The heparin mixture that was analyzed had anywhere from 6 to 30 repeat units of monomer (where the heparin with 30 repeat units would be roughly five times the size of the heparin with six repeat units). a. Which letter most likely represents the peak with 6 repeat units given these heparin polymers were separated with molecular exclusion chromatography? b. Explain your reasoning describing the mechanism of retention in molecular exclusion chromatography. 100 80 60 60 Relative Abundance 40 40 E GH 20 20 B A 36 38 40 42 44 46 48 50 50…
