Boric acid, H3BO3, is commonly used in eyewash solutions in chemistry laboratories to neutralize bases splashed in the eye: H3BO3 (aq) + 3 NaOH (aq) + 3 H₂O (1) + Na3BO3(aq) - A 0.460 M sodium hydroxide solution is used to neutralize a 23.30 mL sample of boric acid. During an experiment, 22.45 mL of sodium hydroxide is required for complete neutralization of the boric acid to a phenolphthalein endpoint. Calculate the number of moles of NaOH used in the reaction.
