A solution of malonic acid, H2C3H2)4, was standardized by titration with 0.1000 M NaOH solution. If 24.91 mL of the NaOH solution were required to neutralize completely 15.78 mL of the malonic acid solution, what is the molarity of the malonic acid solution?
H2C3H2O4(aq) + 2NaOH(aq) -> Na2C3H2)4(aq) + H20(l)
