I'm having a hard time figuring this question out. I really struggle with Ka/Kb values. some help would be amazing. thanks!

This question refers to homework question 3e. The conjugate acid (CH3)2NH2+ would rank where in comparison with the acids in that question in acid strength Between the strongest and second strongest acid Between the second strongest and third strongest acid Between the third and fourth strongest acid Between the fourth strongest and weakest acid It would be the weakest acid Arrange the following acids from strongest to weakest acid. Ka values for weak acids can be found in Appendix H. Kb values for weak bases can be found in Appendix I. The strongest acid is HBr The second strongest acid is HNO2 The third strongest acid is NH4+ HCN The fourth strongest acid is The weakest acid is CH3NH2+ 5/5 HP
