A student tried this identical procedure with a slight modification on a gel antacid. The student dissolved 3.00 mL in 25.00 mL of a standardized HCl solution containing 1.727 *10^-2 mol of HCl. The back titration of the excess HCl required 4.62 mL of 1.015M NaOH solution.

a) Compute the molar concentration of the HCl solution that the student used.

b) Compute the number of moles of HCl neutralized by the antacid tablet.

c) Compute the volume of the effectiveness of the gel.
