A Brand X antacid tablet was analyzed by a student following the procedure used in this experiment. The student dissolved the tablet in 25.00 mL of a standardized HCL solution containing 1.627 x 10^-2 mol of HCL. The back-titration of the excess HCL required 7.83 mL of 1.035M NaOH solution.
(a) Calculate the molar concentration of the HCL solution that the student used.
(b) Calculate the number of moles of HCL neutralized by the antacid tablet.
