I've noticed that recently most of my chemistry questions that get answered have also been incorrect. I cant help but feel like this is a discrepncy between either the methods used, or the values of the refreances when choosing Ka,Ksp,Kb, costants of the nature. In order to avoid this I will post 2 pictures. The fisrt one will be the question I am asking, and the second one will be a worked question of similar nature that I missed. I will also post the refrences that I am using. Please use the numbers off those refernces or the answer will be wrong. Thanks
