what is the average volume of vinegar needed to exactly neutralise 10.0mL of NaOH (aq)?

What's the strength of the vinegar? It comes in 3%, 4%, 5% and perhaps others. Find the strength, convert % to molarity, find the strength of NaOH (the molarity), then Mvin x Lvin = MNaOH x M NaOH. Solve for the one unknown.
