What is the freezing point of a solution prepared from 50.0 g ethylene glycol and 85.0 g H2O Kf of water is 1.86 Celsius?
50g C2H6O2(1 mol C2H6O2/62g C2H6O2)= .81mol C2H6O2 (.81mol C2H6O2/.085kg H2O)=9.53m Kf=1.86 C/m delta t=(1.86 C /m)(9.53m)= 17.7 C t=(0 C-17.7C)=-17.7 C is the freezing point of the solution.

What is the freezing point of a solution made by dissolving 352 g of ethylene glycol C2H6O2 in 648 g of water The freezing point of pure water is 0.0ºC and Kf of pure water is -1.86ºC m?
-10.6c <--- LOL, no. The correct answer is -16.3°C
The density of a 20 percent by mass ethylene glycol solution in water is 1.03gml Find the molarity of the solution?
(0.23)(1.04g/mL)(1000mL/L)(1 mol C2H6O2/62g C2H6O2) = 3.86 M
How many grams of ethylene glycol automobile antifreeze C2H6O2 dissolved in 3.80kg of water is needed to lower the freezing point of water in an automobile radiator to 21.0C?
None. The freezing point of pure water is already lower than that.
What is the classification for C2H6O2?
The classification for C2H6O2 is a molecular compound. This is the chemical formula for ethylene glycol which has non-dissociating bonds.
