The concentration of a sodium hydroxide solution is determined by titrating it against a sample of potassium hydrogen phthalate (KHP). KHP is a weak acid with one hydrogen and a molar mass of 204.22 g/mole. In the titration, 20.46 mL of the sodium hydroxide was used to react with 0.1082 grams of KHP. What is the molarity of the NaOH?

0.1082 g KHP * (1 mol / 204.22 g) = 5.298 * 10^-4 mol KHP
5.298 * 10^-4 mol KHP * (1 mol NaOH / 1 mol KHP) =  5.298 * 10^-4 mol NaOH
5.298 * 10^-4 mol NaOH / 20.46 ml * (10^3 mL / 1 L) = 2.590 * 10^-2 M NaOH, or 0.02590 M
