what mass of acetic acid will produce 2.5L of solution having a pH of 5.5?

Not sure how to solve this without given Ka

You need the Ka to solve that. If it is in a textbook then probably they have some table on a different page that has the Ka

It's in a trial paper, I don't have the solutions tho

Yeah I would assume you need Ka. Is that the exact wording of the question? (Maybe the teacher just made a mistake and put a question for an acid and thought it was a strong acid is also another possibility)

Yeah that was the exact wording, if you treat it as a strong acid, none of the answers line up (it's MC). Don't worry, it's probably a mistake.
Thanks for your help
