Thank you! Now I am having problems with part e.
I put in the wrong numbers for the second part.
I can't figure out how to get the initial pH. Also, when I tried part B I used 21.0 mL*.100M=XmL*0.130 and it wasn't the correct answer.
i tried that but it says its wrong
thankyou for finding those websites for me they are a great help. i looked at those myself but i wasn`t sure if they were right. thanks again!
