One of the more common agents for standardizing solutions of potassium hydroxide (KOH) is potassium acid phtalate (KHC8H4O4), or, more accurately, potassium hydrogen phthalate. From the following data, determine the average molarity of a KOH solution that was standardized with KHP.

Trial A: 45.12 mL of KOH solution neutralized 0.2573 g of KHP

Trial B: 48.89 mL of KOH solution neutralized 0.2250 g of KHP

Trial C: 45.50 mL of KOH solution neutralized 0.2502 g of KHP
