Antifreeze in water problem

  1. Nov 10, 2008 #1
    1. The problem statement, all variables and given/known data
    your car's radiator uses a mixture of antifreeze (C2H6O2) in water to both lower the freezing point and raise the boiling point of the solution. how cold could it get before a 10 mass % solution of antifreeze in water would freeze? (Kf(H2O)=1.86'C/m)

    2. Relevant equations

    3. The attempt at a solutiondont know where to start

    but what am i looking for?the new freezing point?

    yes, the point at which a solution freezes is defined as it's freezing point. That's what you asked.
