Ethanol has a density of .789g/mL, if a bottle of 100-proof vodka is left outside where the temperature is -15C would it freeze; also what is the boiling point of the vodka?

For the freezing one I said no, i said this because i found the Delta T [used 100grams as a base and figured out molality so I could use Delta T=iKfm] to be about 43, I then subtracted 43 from the normal melting point of ethanol [-117.3C] and got -74.3C.

For the second one I used Delta T but for Delta T =iKbm this time and got 26.35; I then subtracted that from the normal boiling point of ethanol which is 78.4C and

got 52.05C to be the Boiling point; Is this correct?
