1. Calculate the number of moles of HCl neutralized per gram of antacid. (Weight Effectiveness) 2. Calculate the average cost of antacid tablet that would be needed to neutralize 1.00 mole of HCl. (Cost Effectiveness) 3. The HCl concentration in a hyperacidic stomach is 0.03M. The volume of liquid in the stomach is 300mL. How many tablets of the antacid which you analyzed would have to be taken to bring the concentration of HCl in the stomach to a more normal level of 0.0003M? Could someone just tell me the steps to do each problem? Thank you so much in advance.
