Great job!
I noticed you made a few mistakes, however you caught all of them by reviewing your work. I commend you in that.
Good job on showing both ways on arriving at the right answer.

in the video, pKa was looked up in a chart in the book... will this be given to us during the final or is this something we have to memorize? What chart exactly also??

I don't think we need to memorize the chart. Ka or Kb will be given in the exam. There are two charts in the chapter 12 of the textbook, including some Ka(Kb) for some common weak acids(bases).
