The absorbance of a liquid sample of FITC was found to be 0.558. Given that the path length used for the determination was 2 cm, and assuming that the molar extinction coefficient for FITC is as given in Section 8.5.2, what was the molar concentration of FITC in the liquid sample?

For a path length of 3 cm and a molar extinction coefficient for TRITC as given in Section 8.5.2, calculate the molar concentration of TRITC in a liquid sample that will result in the absorption of 65% of the light received by the sample.
