Which of the following concentration terms depends on temperature?
Options
Option A
Molality
Option B
Mole fraction
Option C is correct
Molarity
Option D
Mass percentage
Explanation
Molarity depends on the volume of the solution, and volume changes with temperature due to thermal expansion/contraction. Molality, mole fraction, and mass percentage are based on mass, which remains constant regardless of temperature changes. Therefore, Molarity is temperature-dependent while the others are not.
