Assertion (A): A one molal solution prepared at will retain the same molality at provided there is no loss of solute or solvent on heating.
Reason (R): Molality is independent of temperature.
Reason (R): Molality is independent of temperature.
View answer and explanation
Correct option: A
Both (A) & (R) are true and the (R) is the correct explanation of the (A)
Option A (Both (A) & (R) are true and the (R) is the correct explanation of the (A)) is correct because molality is defined as moles of solute per kg of solvent, which is independent of temperature, and this explains why molality remains constant with temperature changes.
