A chemist must prepare 200.0 ml of nitric acid solution with a pH of 1.00 at 25 °C.
He will do this in three steps:
• Fill a 200.0 mL volumetric flask about halfway with distilled water.
• Measure out a small volume of concentrated (6.0 M) stock nitric acid solution and add it to the flask.
• Fill the flask to the mark with distilled water.
Calculate the volume of concentrated nitric acid that the chemist must measure out in the second step. Round your answer to 2 significant digits.
