# A solution is made by dissolving 55 g of KNO_3, in 100 g of water at 60 degrees C. Is this solution saturated, unsaturated, or supersaturated?

$\text{Potassium nitrate}$ is exceptionally soluble in water. Your solution is $\text{UNSATURATED}$.
As to $\text{supersaturation}$, this occurs when the solvent contains a greater quantity of solute than would be in equilibrium with undissolved solute. See this site for details on potassium nitrate solubility, which give the values for $\text{saturated solutions}$. As a chemist, as a physical scientist, you should inform your argument with numbers, with quantitative data.
