You have carried out an experiment using the spectrophotometry concept. A solutioncontaining compound X is mixed with reagent 1 and then reagent 2. This mixture produces ablue colour whose absorbance (A) could be read at 550 nm. The results are shown below If the standard solution (compound X) used have a concentration of 1 mM: 3. If the absorbance was read using 1 cm diameter cuvettes, calculate the molar extinctioncoefficient for compound X in the solution. State the unit for the coefficient.

For this experiment I prepared two solutions: each was an injection of 15 microliters of pure acetic anhydride into 3.0 milliliters of either light water (H2O) or heavy water (D2O). I then measured the absorbance of the solution in a quartz cuvette at 250 nm (UV light) over time to monitor the decay of acetic anhydride. Suppose you ran the experiment with 15.9 microliters of acetic anhydride in 7.5 milliliters of water. What would be the initial concentration [in mol/L] of the solution? The density of acetic anhydride is 1.08 g/mL and its molar mass is 102.09 g/mol.
