A student prepares a dilute solution of sodium hydroxide, NaOH(aq), starting with 6 M so- dium hydroxide. She then titrates a 1.372 g sample of KHP with the dilute sodium hydroxide solution, NaOH(aq), to a phenolphthalein end point. If the titration required 21.84 mL of sodium hydroxide, NaOH(aq), calculate the molar concentration of the sodium hydroxide solution, NaOH(aq). (Remember that KHP is potassium hydrogen phthalate, KHC,H,O, NOT potassium hydrogen phosphorus!)
