Question

The freezing points of five solutions of nonvolatile substance A is given as

(A) -1.10 ⁰C,
(B) -1.25 ⁰C,
(C) -2.25 ⁰C,
(D) -3.50 ⁰C, and
(E) -5.50 ⁰C.

Which solution has the highest concentration in molality?
A) Solution A
B) Solution B
C) Solution C
D) Solution D
E) Solution E

Answer 1

Solution A has the highest concentration in molality as it has the lowest freezing point of -1.10 ⁰C.

Step-by-step explanation:

The freezing point depression is directly proportional to the molality of the solution. The solution with the highest molality will have the lowest freezing point. Therefore, the solution with the highest concentration in molality is Solution A, which has a freezing point of -1.10 ⁰C.
