Homework Help: Chemistry

Posted by Angelica on Monday, April 19, 2010 at 12:36am.

A popular brand of automobile radiator antifreeze advertises that their product (ethylene glycol; C2H6O2) provides engine protection from temperatures of -64C to 135C when mixed with water in a 50%/50% mix. What is the boiling point elevation and freezing point depression provided by such a mixture?

I'm not sure whether or not I'm supposed to know that Kf of ethylene glycol is 1.86 since this is a worksheet that introduces us to colligative properties so I was wondering how I would do this without using that formula? PLEASE AND THANK YOU.
