Potassium hydrogen phthalate (KHP) is used as a primary standard acid to accurately find out the molarity of a NaOH solution via a titration. The formula of KHP is KHC8H4O4 and has a molar mass of 204.23 g/mol. If 11.22 ml of a NaOH solution are required to exactly neutralize 0.477 g of KHP, explain what is the molarity of the NaOH solution?
