A student titrates 60.0mL of HNO3 with 0.03 NaOH. Phenolphtalein is used as the indicator. After adding 42.2mL of NaOH, a color change remains for 25 seconds, and the student stops the titration. According to the data, how many significant figures should be present in the calculated molarity of HNO3?
