Strategy:
 Volume is temperature-dependent (liquids expand/contract with temperature changes), whereas mass is temperature-independent. Any concentration term involving volume will change with temperature.

Analysis:
1. Molarity (): Defined as moles per liter of solution. Since volume changes with , Molarity changes. (Dependent)
2. Mass percentage: Ratio of masses. (Independent)
3. Molality (): Moles per kg of solvent. (Independent)
4. Mole fraction: Ratio of moles. (Independent)
