A chemist must prepare 550.0 mL of sodium hydroxide solution with a pH of 13.00 at 25 He will do this in three steps: • Fill a 550.0 mL volumetric flask about halfway with distilled water. • Weigh out a small amount of solid sodium hydroxide and add it to the flask. • Fill the flask to the mark with distilled water. Calculate the mass of sodium hydroxide that the chemist must weigh out in the second step. Round your answer to 2 significant digits.
