Homework Help: Freezing point

  1. Oct 7, 2008 #1
    1. The problem statement, all variables and given/known data

    1.Antifreeze used in your car is ethylene glycol, HO-CH2-CH2-OH. It is usually diluted 1:1. Assume that you made a solution of 50 g of water (solvent) and 50 g of ethylene glycol (solute). What temperature in Celsius would your car be protected to in cold weather? Assume the freezing point of pure water is 0 degrees Celsius.

    2.Why is the freezing point of pure water determined experimentally instead of just assuming tha it is 0 degrees Celsius?


    2. Relevant equations
    Do i use the formula, delta T = (Kf)(molality)?
