Describe the relationship absorbance and concentration. What constant in the Beer's Law equation measure of the amount of light absorbed by the sample per unit concentration and appropriate path length? Describe the relationship between this magnitude of this constant and a compounds ability to effectively absorb light. Determine the concentration of unknown chlorophyll solution knowing that its absorbance at 662 nm is 0.45. The path length is 1 cm and the molar absorptivity constant is 8.4 times 10^4 M^-1 cm^-1. Show all your work.
