At 23°C, 85.0 grams of NaNO3(s) are dissolved in 100. grams of H2O(l).

Based on Table G, determine the additional mass of NaNO3(s) that must be dissolved to
saturate the solution at 23°C.

Final answer:

Without the actual solubility data for NaNO3 at 23°C, we cannot determine the exact additional mass needed to saturate the solution. If we had this data, we would subtract the current amount dissolved (85 g) from the solubility limit to find how much more is needed to reach saturation.

Step-by-step explanation:

To determine the additional mass of NaNO3 needed to saturate the solution at 23°C, we would need the solubility chart for NaNO3, which is not provided in the given information. However, assuming we have the solubility chart and it shows, for example, that the solubility of NaNO3 at 23°C is 100 g per 100 g of H2O, then the current solution with 85 g of NaNO3 is unsaturated since it has less than 100 g dissolved.

To saturate the solution, you would need to add the difference between the solubility amount and the amount already present. If the chart says 100 g is the saturation point, you would need to add 15 g of NaNO3 to reach the saturation limit (100 g - 85 g = 15 g).

Without the exact solubility data, we can't provide the precise amount needed to saturate the solution. It's crucial to consult a solubility chart for NaNO3 at 23°C to get the accurate data necessary to answer this question.

Anything between 4 and 6 is ok.
