Final answer:
Without specific data on the mass of NaOH used, one cannot accurately determine the volume of water required to prepare an NaOH solution. Typically, NaOH is dissolved in water up to a known volume mark in a volumetric flask.
Step-by-step explanation:
The question asks for the volume of water used to prepare an NaOH solution, which is a common procedure in titration experiments.
To determine the volume of water used, you would need the final desired concentration of the NaOH solution and the amount of NaOH solid that was dissolved. Since the question does not provide specific information on how much NaOH was used, I cannot give an exact volume of water.
However, if we look at the given instructions, such as standardizing NaOH using benzoic acid, and the titration example provided, we usually do not need the volume of water to perform the standardization. The process will typically involve dissolving a certain mass of solid NaOH in a known volume of water to prepare a solution with a desire concentration, for example, a 0.250 M solution, which you will then standardize using a primary standard such as benzoic acid.
The exact amount of water used can vary based on the molarity and the volume of the NaOH solution required for the experiment. In a common laboratory setting, solute (solid NaOH) is weighed and added to a volumetric flask, which is then filled up to a known volume mark with distilled water, thereby giving the final volume of the solution such as 250 mL or 500 mL, rather than adding a measured volume of water to a certain mass of NaOH.
