Thylene glycol c2h6o2 IS used in some antifreeze mixtures protection against freezing to as low as -40 degree C is sought. Determine the numbers of quarts of ethylene glycol liquid density 1.11 g/ml should be mixed with each quart of water that has a density of 1.00 g/ml. The Kf of H2O =1.86 degree C /MOLAL and the freezing point of water is 0.0 degree C also given 1 LITER= 1.06 quarts.
