NaOH is a strong base, so it dissociates completely in water. The concentration of OH- ions in the solution is equal to the concentration of NaOH, which is 0.150 M. The pOH is calculated using the formula pOH = -log[OH-], which gives pOH = -log(0.150) = 0.82. Since pH + pOH = 14 for aqueous solutions at 25°C, the pH is 14 - 0.82 = 13.18.
