Hi,

I need supporting Facts On My Whats % Water Freezes Alcohol!

You need to know freezing point depression constant of water (-1.86 C per mole of solute per kilogram of solvent)

Caluculate molality of solution.
The molality of the solution is moles of solute (alcohol) per kilogram of
solvent.

Please use following website for reference.
