First, we distinguish whether table sugar or table salt will be more soluble. The bonds between the molecules of the table sugar are weaker than the bonds between the molecules of salt. Therefore, it is easier for the sugar molecules to dissolve.
Next, we evaluate the effect of temperature on solubility. As the temperature of a solvent increases, it is able to hold more and more solute. This means that the sample with table sugar kept at the highest temperature will contain the most dissolved solute, and this is sample 1.

Table sugar has the highest solubility.

The ability of the solute to form the solution by dissolving in the solvent is called solubility. The solid, liquid or gas can be used as the solute to form the solution.

How the solubility can be estimated?

The amount of solute that can dissolve easily and readily with the solvent to form the solution is called solubility. The temperature and the pressure plays an important role in the solubility.

In the above-given data, the table sugar has the highest amount of the solute of 80 g that can dissolve in the solvent while the amount of the other solutes is low.

Therefore, option 1 is correct.
