**Question:**b. If the solution volume is 170. mL, what mass of \( \text{Ba(OH)}_2 \) must have been dissolved?**Answer:**Mass = [_____] g---This question is a typical exercise in a chemistry course where students calculate the mass of a solute required to make a specific solution volume. In this case, the solute is barium hydroxide, \( \text{Ba(OH)}_2 \), and the solution volume is given as 170 mL. Students would typically use the molarity equation, \( M = \frac{\text{n}}{\text{V}} \), along with the molar mass of \( \text{Ba(OH)}_2 \) to find the required mass. No graphs or diagrams are included in this exercise. The pH of a solution of Ba(OH)₂ is 10.95 at 25 °C.
