Which of the following concentration terms depends on temperature?

Model Answer & Options

Source: Extra Practice

Molality

Mole fraction

Molarity

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.
