The image they show us is a solubility graph. It tells us the grams of solute that dissolve at a certain temperature. We must first identify the mentioned solute, this is NaNO3. We must draw a vertical line that passes through 30°C and a horizontal line that passes through 90 grams/100g of water.

When tracing the lines we see that the intersection is below the solubility curve of NaNO3. This means that there is less solute than the maximum amount that water can dissolve at 30°C. Therefore, all 90 grams will dissolve and we will have an unsaturated solution.

Answer: Third option. unsaturated
