A chemist must prepare 800.0 mL of hydrochloric acid solution with a pH of 1.90 at 25 degree C. He will do this in three steps: Fill a 800.0 mL volumetric flask about halfway with distilled water. Measure out a small volume of concentrated (9.0 M) stock hydrochloric add 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.
