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.
