A student titrates 60.0 mL of HNO3(AQ) with 0.30 M NaOH(AQ). Phenolphthalein is used as the indicator.
After adding 42.2 mL of NaOH(AQ), a color change remains for 25 seconds, and the student stops the
titration. Write a balanced equation and calculate the molarity of the of HNO3(AQ), with sig figs and units
