Which of the following solutions will have the lowest freezing point?

A1.0 mol/kg sucrose (C12H22O11)
B1.0 mol/kg lithium chloride (LiCl)
C1.0 mol/kg sodium phosphide (Na3P)
D1.0 mol/kg magnesium fluoride (MgF2)

Verified Answer :

C1.0 mol/kg sodium phosphide (Na3P) 

This is because it will produce 4 ions, and thus has the highest molalitiy. (more particles in solution lowers the freezing point) 

remember if you ever need anything and you dont want to waste points you can just post it on my pfp or message me the question
