Two drops of 0.20 M imidazole solution were added to a solution containing ferrihemoglobin. The mass of the ferrihemoglobin solution was measured before the addition of the imidazole and the mass of the final solution was measured after adding the imidazole. The results are recorded in the following table: Drops of Imidazole Solution Mass of Total Solution (g) Mass of Imidazole Solution Added (g) 0 2.550 0 2 2.632 0.082 Assuming that the densities of all solutions are identical, calculate the concentration (in molarity) of imidazole in the final solution after the 2 drops of imidazole were added. (Since the experiment has been designed to ensure that imidazole is the excess reagent, the concentration calculated can be assumed to be the equilibrium concentrations as well.)
