I will not say for sure, but my guess is that by water would be very difficult. Sodium Acetate will readily dissolve in water. therefore, it's volume by water displacement would not work. The only way you can determine an item's volume by water displacement is if it is insolubable and more dense than water. I believe this is the answer your instructor is looking for.

If you look at solubility rules, sodium compounds are ALWAYS soluble in water, so if you tried to determine the displacement of a certain mass of sodium acetate in water, the compound would immediately begin disolving in water. It would be impossible, therefore, to use water to determie the density of sodium acetate. It would be better to use some type of non-polar solvent which is not very volatile.

density of a solid is usually determined by measuring its volume using water displacement. This means that you take a known volume of water and add your solid of interest to it. By adding this solid you would change the volume of the water. The amount of change in volume would be the volume of your solid of interest. of course you would need to measure the mass of your solid of interest as well density = mass/volume however sodium acetate dissolves in water so that would not allow you to determine it density because no water would be displaced...
