Option 1: When dissolved, sugar molecules have more opportunities to bond with positive-negative water molecules. Therefore, sugar dissolves faster than salt, because its component molecules are more soluble in water.
❤️
Option 2: Sugar can dissolve easier than salt because when you add 8 spoons of salt into water the salt already starts to stay in the bottom of the cup. And, when you add 30 spoons into water the sugar just starts to stay in the bottom of the cup. It’s almost the same.
Hope it helps.
Have a nice day!~ ￣▽￣❤️
