Astudent was comparing the solubility of equal amounts of table salt and table sugar at different temperatures. the table below shows the four samples that the student used and the temperature of the water that they were dissolved in. sample name chemical formula temperature of water (°c) 1 table sugar c12h22o11 80 2 table sugar c12h22o11 45 3 table salt nacl 55 4 table salt nacl 63 which of the samples most likely had the highest solubility?

The sample that has the highest solubility is THE FIRST SAMPLE [TABLE SUGAR NO 1].
Solubility refers to the quantity of a solute that will dissolve in a given volume of solvent at a given temperature and pressure. The question above tells us that equal amounts of sugar and table salts were used. But looking at the table given in the question, you will see that sample 1 has the highest amount of solute that dissolve, that is 80,  the rest of the samples have values that are lower than that.
