Homework Help: Chemistry

Posted by Yo on Wednesday, October 28, 2009 at 8:53pm.

Hi Dr. Bob, this is a chemistry question. I don't know how to go about solving this problem:

What is the pH of the solution created by combining 11.40 mL of the 0.10 M NaOH(aq)with 8.00 mL of the 0.10 M HC2H3O2(aq)?

Here's what I have so far:
(0.10M NaOH)(0.0114L)= 0.00114 mol NaOH
0.00114 mol NaOH/(0.0114+0.008)= 0.0588M NaOH

(0.10M HC2H3O2)(0.008L)= 0.0008 mol HC2H3O2
0.0008mol HC2H3O2/(0.0114+0.008)= 0.0412M HC2H3O2

any idea where to go from here? thanks
