Titration Calculation Help

I'm practising my chemistry practical exam and I found a titration which requires you to find the total acidity in terms of moles of available protons per dm³ of solution of a mixture of ethanedioic acid and ethanoic acid, by titration with sodium hydroxide solution of concentration 0.100 moldm^-3.

If the titre value for the NaOH is 26.10 cm³, how would you go about working it out since it's a mixture of two acids?

I started out by finding the moles of NaOH in 26.10 cm³which would be 0.00261 moles. If it were a solution of one of the acids the calculation would be simple but I'm getting lost since it's a binary mixture. :s-smilie:

It matters not a whit that there be two acids as all you require is moles of hydrogen ions ...
