A chemist dissolves 1 mol NaCl in a 2.0-kg sample of water, then dissolves 1 mol sucrose in another 2.0-kg sample of water. Why does the NaCl solution have a lower freezing point? Ions require more energy to dissolve than molecular compounds do.

The NaCl solution has a greater mass than the sucrose solution.

The NaCl solution has twice the number of dissolved particles as the sucrose solution.

Ions strengthen a liquid more than molecular compounds do.
