I can't give you a "correct" answer with the information given, but I can show you how to solve it, which I did.
This is a really annoying unit conversion problem before we can even solve it, hold on:
You usually need the volume of one or the other solution in order to accurately solve this problem, but I will assume we are trying to neutralize
This appears to be a bit unreasonable, so perhaps in your problem the amount of citric acid needing to be neutralized is larger.
The required volume is
Step 1. Write the balanced equation for the reaction
Citric acid is a tribasic acid. Its titration curve will look something like the one below.
Step 2. Calculate the moles of
Step 3. Calculate the volume of
Note: The answer can have only one significant figure, because that is all you gave for the concentration of the
However, I calculated the answer to two significant figures.
