If the solute is Magnesium Chloride (MgCl_2), which is expected to completely dissociate, how will the boiling point of this solution compare to a 0.1 m solution of glucose?

1. The glucose solution will have a higher boiling point because it has a larger molecular weight.
2. Both solutions will have the same boiling point because they have the same molality.
3. The MgCl_2 solution will have a higher boiling point because it produces three times as many particles.
4. The MgCl_2 solution will have a lower boiling point because ionic solutes reduce the surface area for evaporation.
