Preparing a strong base solution with a given pH A chemist must prepare 700.0 mL of potassium hydroxide solution with a pH of 12.00 at 25 °C. She will do this in three steps: ⚫ Fill a 700.0 mL volumetric flask about halfway with distilled water. • Weigh out a small amount of solid potassium hydroxide and add it to the flask. • Fill the flask to the mark with distilled water. Calculate the mass of potassium hydroxide that the chemist must weigh out in the second step. Round your answer to 2 significant digits. g ☐ x10 ☑
