The concentration of a sodium hydroxide solution is determined by titrating it against a sample of potassium hydrogen phthalate (KHP). KHP is a weak acid with one hydrogen and a molar mass of 204.22 g/mole. In the titration, 20.46 mL of the sodium hydroxide was used to react with 0.1082 grams of KHP. What is the molarity of the NaOH?
