An aliquot of a nitric acid solution which is having 25.0 mL of unknown concentration is pipette into a 125 mL flask, and 2 drops of phenolphthalein are added. 16.22 mL of sodium hydroxide solution is used to titrate the nitric acid solution (the analytic). If 12.75 mL of the titrate is dispensed from a burette in causing a color change of the phenolphthalein, determine the molar concentration of the nitric acid solution?
