Homework Help: Chemistry

Posted by ANONYMOUS on Saturday, December 1, 2012 at 10:13pm.

25.00 mL of a solution of oxalic acid are titrated with 0.2586 m NaOH (aq). The stoichiometric eend point is reached when 43.42 mL of the solution of base is added. What is the molarity of the oxalic acid solution? Oxalic acid reacts with sodium hydroxide as shown:
H2C2O4(aq) + 2 NaOH(aq) --> Na2C2O4(aq) + 2 H2O (l)

I thought I had this figured out last night, but now as many times as I try I can only come up with .044
I had .01123
