An analyst was attempting to determine the percent KHP in an unknown sample. The analyst found the molarity of the standardized NaOH solution to be 0.1022 mol/L. Three aliquots of the unknown sample having weights of 0.8186 g, 0.9364 g, and 0.8719 g were titrated with the NaOH solution requiring 18.29 mL, 22.63 mL, and 21.09 mL, respectively. From these data, determine the average percent KHP in the unknown sample.
