Q:

Ethylene glycol is used as an antifreeze in a cold climate. Mass of ethylene glycol which should be added to 4 kg of water to prevent it from freezing at –6°C will be: (Kf for water = 1.86 Kg/mol and molar mass of ethylene glycol = 62 kg/mol)

A) 204.60 g	B) 304.30 g
C) 804.32 g	D) 400.00 g

Answer & Explanation Answer: C) 804.32 g

Explanation:

$∆ T_{f} = k_{f} . m$

for ethylene glycol in aq. solution

$∆ T_{f} = k_{f} \frac{w}{m o l . w t} \times \frac{1000}{w t . o f s o l v e n t} 6 = \frac{1.86 x w x 1000}{62 x 4000}$

=> w = 800 g

So, the weight of solute should be more than 800 g.
