A chemist must prepare 300.0 mL of hydrochloric acid solution with a pH of 1.00 at 25 °C. He will do this in three steps: • Fill a 300.0 mL volumetric flask about halfway with distilled water. • Measure out a small volume of concentrated (9.0M) stock hydrochloric acid solution and add it to the flask. • Fill the flask to the mark with distilled water. Calculate the volume of concentrated hydrochloric acid that the chemist must measure out in the second step. Round your answer to 2 significant digits.
