Calculate the volume of 6 M NaOH required to react completely with the amount of methyl salicylate you used. How much of the 6 M NaOH that you used was in excess of the theoretical amount? We started off with 2.00 mmol or 0.002 moles of methyl salicylate and we added 2.5 ml of aqueous 6 M sodium hydroxide
