C2h6o2 is infinitely miscible(soluble) in water. ethylene glycol is a nonelectrolyte that is used as antifreeze. what is the lowest possible melting point for engine coolant that is 30% ethylene glycol? the kf for h20 is 1.86 c/m. expert answer 100% (7 ratings) previous question next question get more from chegg

-12.85 °C is the lowest possible melting point for engine coolant that is 30% ethylene glycol.

Explanation:

where,

=depression in boiling point

i = van't Hoff factor = 1 (organic compounds)

Mass of ethylene glycol = 30 % of 100 g solution :

=

Mass of water=100 g - 30 g = 70 g = 0.070 kg (1 kg = 1000 g)

= freezing point constant = 1.86 °C/m

m = molality

Now put all the given values in this formula, we get:

Freezing pint of pure water = T = 0°C

Freezing point of 30 % ethylene glycol solution =

-12.85 °C is the lowest possible melting point for engine coolant that is 30% ethylene glycol.
