The moles of HCl are 0.01875 and the moles of NaOH are 0.0352. NaOH is in excess, so the solution is basic. The remaining moles of NaOH are 0.01645, and the concentration in the final volume (125 mL) is 0.1316 M. The pH is calculated using pOH = -log[OH-], and then pH = 14 - pOH, resulting in a pH of approximately 13.12.
