A chemist must prepare 600.0 mL of hydrobromic acid solution with a pH of 1.90 at 25 °C. He will do this in three steps: • Fill a 600.0 mL volumetric flask about halfway with distilled water. • Measure out a small volume of concentrated (8.0M) stock hydrobromic acid solution and add it to the flask. • Fill the flask to the mark with distilled water. Calculate the volume of concentrated hydrobromic acid that the chemist must measure out in the second step. Round your answer to 2 significant digits. O mL
