Hey, thank you for reaching out!
To explain why one molecule dissolves more easily in water, we need to look at its composition. The salt molecule contains strong bonds between Na+ and Cl- as atoms in sugar are not bound as strongly. Therefore, bonds are easier to break making the molecule more soluble. Also, salt ions are smaller than sugar ones. It is then easier for water to stabilize each ion. This being said, we ought to remember that, each, sugar and salt are very soluble molecules compared to other bigger/stronger molecules.
Hope it helps!
