Antifreeze in cars is usually made by mixing ethylene glycol, hoch2ch2oh, with water to make a 50.% meolume solution. if the specific gravity of ethylene glycol is / 1.113, calculate a) the boiling and b) the freezing point of this solution. assume that water is the solvent. 4. using the solution made in problem 3, calculate the a) k and b) ke for ethylene glycol assuming it is the solvent. 5. calculate the molecular mass of ethylene glycol if a 150 g sample is placed into 250 g of ethyl alcohol, which has a boil ing point of 78°c and the resulting mixture has a boiling point of 89.8°c. 6. based on the formula for ethylene glycol, hoch2ch2oh, what is its calculated molecular mass to 3 decimal places? am 5 ond 6 do not match exactly?
