Antifreeze protects a car from freezing and from overheating. Calculate the freezing-point depression of a solution containing exactly 100. G of ethylene glycol (C2H6O2) antifreeze in 0.500 kg of water. Kf of water is: -1.86 C/m

Question

Please show work!!

Answer 1

dT = Kf*m
m = molality = mols/kg solvent
You have how many mols. mols = grams/molar mass = ?
Then m = mols/0.5
Then substitute Kf and m and solve for delta T.
