- Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R) Assertion (A): At 10° C, the density of a 5 M solution of KCl [atomic masses of K and Cl are 39 35.5 g mol -1. The solution is cooled to -21° C. The molality of the solution will remain unchanged. Reason (R): The molality of a solution does not change with temperature as mass remains unaffected with temperature. In the light of the above statements, choose the correct answer from the options given below:
