Question

A solution of the primary standard potassium hydrogen phthalate, KHC8H4O4,KHC8H4O4, was prepared by dissolving 0.4877 g of potassium hydrogen phthalate in about 50 mL of water. The molar mass of potassium hydrogen phthalate is 204.22 g/mol. Titration with a KOH solution required 23.41 mL23.41 mL to reach a phenolphthalein end point. What is the molarity of the KOHKOH solution?
