Answer:
Weight
Step-by-step explanation:
Weight does not have any effect on solutbility.
For gases their solubility relies a lot on pressure exerted. At higher presure, gases dissolves more readily than ever. The relationship between solubility and pressure is a direct one.
Higher surface area facilitates the rate of a reaction and in essence, helps to dissolve more solute. Surface area exposes a solute to the action of more solvent which would aid solutbility.
Temperature has a high effect on solubility. An increase in temperature would make more solute dissolve in it.
