Hi, I can't seem to get these questions right. Any help would be really appreciated!
1. What is the pH of 0.33 mol/L methylammonium bromide, CH3NH3Br (Kb of CH3NH2 = 4.4 Ã 10â4)?
2. A 0.299 mol sample of HX is dissolved in enough H2O to form 655 mL of solution. If the pH of the solution is 3.60, what is the Ka of HX?
