Homework Help: chemistry

Posted by UN on Wednesday, July 9, 2008 at 12:19am.

What is the pH of the solution created by combining 2.80 mL of the 0.10 M NaOH(aq) with 8.00 mL of the 0.10 M HCl(aq)? with 8.00 mL of the 0.10 M HC2H3O2(aq)?

mL of NaOH pH w/HCl pH w/HC2H3O2
2.80 ? ?

okay, so i tried m1v1=m2v2 and when i got m2 i would input it in -log(H+) to get the ph but it is wrong? the question asks for two reachants one with only HCl and then HC2H3O2 added as well.
