To standardize a solution of NaOH before using it in a titration of an unknown acid, you dissolve 3.56 grams of potassium hydrogen phthalate (KHP) into 100 mL of H2O. You then titrate the KHP with your sodium hydroxide solution and reach the endpoint after adding 20.9 mL of NaOH. What is the molarity of your sodium hydroxide solution? (Molecular Mass of KHP = 204.22 g/mol)
