What is the pH and equivalence volume of NaOH at this point? 3. a. At the equivalence point, how many moles of 1 M NaOH were added to the flask. To get the number of moles, multiply the molarity by the number of LITERS of NaOH added. b. At the equivalence point, the number of moles of NaOH equals the number of moles of HCl in the flask.
