Fourdrops of a 0.45M imidazole solution were added to a solution in a cuvette containing ferrihemoglobin. The mass of the ferrihemoglobin solution in the cuvette was measured to be 2.170 g initially and 2.252 g after the addition of the stock imidazole solution. What is the molar concentration of imidazole in the final solution after the 4 drops of stock imidazole were added to the ferrihemoglobin solution in the cuvette?
