Question

A chemist must prepare 450.0 mL of hydrobromic acid solution with a pH of 1.60 at 25 °C.
He will do this in three steps:
• Fill a 450.0 mL volumetric flask about halfway with distilled water.
• Measure out a small volume of concentrated (6.0M) 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.
