The initial volume of a hydrochloric acid solution is 98 mL with a concentration of 0.945 M HCl. An antacid tablet is added to the solution. Then a back titration is done with a 0.78 M NaOH solution. The initial volume of the sodium hydroxide is 32.3 mL and after the titration the final volume is 112.4 mL. What are the number of moles of antacid?
