None of the solutions would be considered supersaturated because the solubility of sodium in water is only 76 grams per 100 grams of water, regardless of the amount of sodium acetate or volume of water present in the solutions. Supersaturation occurs when a solution contains more solute than it should be able to dissolve at a given temperature and pressure, but this is not the case in any of the given options.
