i'm sorry...i totally missed a part of it...
a volume of 15mL of 0.40M NaOH is added to 25mL of 0.40M HF solution. assume volumes are additive

I think there is some information missing; Did they give any starting quantities of the two reactants and did they give a volume of the solution (or molar concentrations)?
