Assertion: On increasing the temperature, the millimoles of solute, milliequivalent of solute, molality, mole fraction of solute and

\%

by weight does not change.
Reason: Each of these involves only masses of solute and solvent.

View answer and explanation

Correct option: C

Both Assertion and Reason are correct and Reason is correct explanation of Assertion

Option C is correct because both the assertion and reason are correct, and the reason accurately explains why the listed concentration units are independent of temperature.
