A chemist must prepare 250.0 mL of nitric acid solution with a pH of 1.40 at 25 "C. He will do this in three steps: • Fill 250.0 ml volumetric flask about halfway with distilled water. • Measure out a small volume of concentrated (9.0M) 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.
