One of the two most common ingredients in medication designed for the relief of excess stomach acidity is the tri-protic basealuminum hydroxide, Al(OH)3 (78.0g/mol). If a patient suffering from a duodenal ulcer displays ahydrochloric acid (36.5 g/mol) concentration of 9.28 x10-3 M in his gastric juice and he produces 2.80 liters of gastric juice per day, explain how much medication(in mL) containing 2.60 g Al(OH)3per 100 mL of solution must he consume per day to neutralize the acid?
