Hmm I sense something weird. But I was looking for a picture of a buret to show you that its scales are different than on most equipment: http://cbse.meritnation.com/img/lp/1/11/5/194/671/1334/1345/25-5-09_LP_Utpal_Chem_1.11.5.1.1.2_SJT_SS_html_m7337528f.png From what I know, the question might have it wrong. But, I think you just have to find the difference between the initial and final volume of NaOH.

I have the final volume - intial volume = volume of the titrant. 
34.0mL-0=34.0mL NaOH
34.0mL/1000mL X 0.25 mol NaOh X 1 mol H2SO4/2 mol NaOH= 0.21 M H2SO4.

Um, what are you doing? Are you looking for the amount of product?

The question asks determine the volume of sodium hydroxide added to the flask from the buret.

wolfe8 · Answer

Yes. Thus, you just minus the initial volume given with the final volume also given.
