Ethylene Glycol Is Used in Automobile Radiators as an Antifreeze $\circ$

Ethylene glycol is used in automobile radiators as an antifreeze. What will the freezing point of an antifreeze solution be if 2.5 L of ethylene glycol are mixed together with 2.5 L of water? The following information may be helpful to you. Ethylene glycol has a very low vapor pressure and is essentially nonvolatile.
molar mass of ethylene glycol = 62.1 g/mol
Van 't Hoff factor = 1
Density of ethylene glycol = 1.11 g/mL
Density of water = 1.00 g/mL
K_f for water =1.86 ^$\circ$ C kg/mol

A) (-39 ^$\circ$ C)
B) (-16 ^$\circ$ C)
C) (-1.6 ^$\circ$ C)
D) (-33 ^$\circ$ C)
E) (-24 ^$\circ$ C)
