A solution of malonic acid H2C3H2O4 was standardized by titration with .1000M NaOH solution. If 20.76mL of the NaOH solution were necessary to neutralize completely 13.15mL of the malonic acid solution, define what is the molarity of the malonic acid solution?
H2C3H2O4 + 2 NaOH ---> Na2C3H2O4 + 2 H2O
