Potassium hydrogen phthalate, (KHC8H4O4, molar mass = 204.2 g/mol) is a primary standard acid that reacts with sodium hydroxide in a 1:1 stoichiometric ratio. A sample of the acid weighing 0.4521 g was titrated with NaOH, requiring 22.61 mL to reach the endpoint. Calculate the molar concentration of the NaOH solution.
A. 20.00M
B. 0.05001M
C. 10.22M
D. 0.09792M
