The antifreeze solution used in the majority of car radiators is a mixture of equal volumes of ethylene glycol and water, with minor amounts of other additives that prevent corrosion. a) What is the mole fraction of ethylene glycol, C2H4(OH)2, in a solution prepared from 2.22 × 103 g of ethylene glycol and 2.00 × 103 g of water?
Q6-What is the molality of a solution prepared by dissolving 72.8 g of ethylene glycol, HOCH2CH2OH, in 1.60 L of water? Assume the density of water is 1.00 g/mL.
Antifreeze is ethylene glycol, C2H4(OH)2 and is made from ethylene which is produced from oil. It is miscible in water (i.e., dissolves in any proportion), does not dissociate in water, is toxic to drink (especially to dogs who like the sweet taste), but fortunately is biodegradable and at normal automobile operating temperatures, is not flammable. It can prevent freezing of the automobile cooling system down to -34oF and the advertisement says “winter - summer automobile coolant” — it also prevents...
