What would be the freezing point of a 1.7 mole aqueous ethylene glycol solution? the freezing point depression constant for water = 1.86 degrees celsius per mole.

a) 3.2°c

b) – 1.1°c

c) 0.0°c

d) – 3.2°c

The freezing point of a 1.7 mole aqueous ethylene glycol solution is 3.2°C

Explanation:

Moles present in aqueous ethylene glycol solution= m=1.7

Depression constant for water = = 1.8 deg C/m

According to formula  

=1.8* 1.7

=3.2

Hence the freezing point of aqueous ethylene glycol solution is 3.2°C
