A second analyst was attempting to determine the percent KHP in an unknown sample, similar to that in the CEM 262 laboratory experiment 1. The analyst found the molarity of the standardized NaOH solution to be 0.1016 mol/L. Three aliquots of the unknown sample having weights of 0.8181 g, 0.9393 g, and 0.8719 g were titrated with the NaOH solution requiring 20.00 mL, 22.39 mL, and 22.14 mL, respectively. From these data, determine the average percent KHP in the unknown sample.
