What volume of ethylene glycol (C2H6O2), a nonelectrolyte, must be added to 13.7 L of water to produce an antifreeze solution with a freezing point of 30.0¡ÆC? (The density of ethylene glycol is 1.11 g/cm3, and the density of water is 1.00 g/cm3.)

delta T = Kb*molality
You know delta T, I assume you have Kb (the freezing point depression constant), calculate molality.
Then molality = grams/kg solvent.
You know molality and Kg solvent, calculate grams.
From grams, use density to determine volume. Post your work if you get stuck.
