Homework Help: chem

Posted by alicia on Tuesday, February 12, 2008 at 11:07am.

The "proof" of an alcoholic beverage is twice the volume percent of ethanol, C2H5OH, in water. The density of ethanol is 0.789g/mL and that of water is 1.99g/mL. A bottle of 100-proof rum is left outside on a cold winter day. a) Will the rum freeze if the temperature drops to -18 degrees C?
b) Rum is used in cooking nd baking. At what temperature does 100-proof rum boil?

I thought I should use the freezing point depression equation but then I don't know what information I need.
