Ethylene glycol is the primary ingredient in antifreeze, has the chemical formula C2H6O2. The radiator fluid used in most cars is a half & half mixture of water and antifreeze (by mass). If Kf=1.86 C/m and Kb=0.512 C/m,
What is the freezing point of the radiator fluid?
What is the boiling point of the radiator fluid?
The direction I was headed with this is trying to calculate the molality with what I have here and I used a 1:1 ratio for the C2H6O2 and the water, but that gives me .06206 kg/mol. Help?
