To precipitate as Ag2S(s), all the Ag+ present in 338 mL of a saturated solution of AgBrO3 requires 30.4 mL of H2S(g) measured at 23 ∘C and 748 mmHg. What is Ksp for AgBrO3? **This solution is posted under the text book solutions (General Chemistry, 10th ED. Chapter 18, question 13), but I can't quite follow the process. I'm hoping someone can break apart the steps a bit more.
