(For H2O, Kb=0.52 C/m Kf= 1.86 C/m

I can't even find the formula for this in my book, please help :(

**DrBob222**, Thursday, January 24, 2013 at 10:42pmYou need to know the mass of the radiator fluid, take 50% for mass ethylene glycol and 50% H2O.

Then mols glycol = grams/molar mass

molality = mols glycol/kg solvent

delta T = Kf*m

Subtract delta T from 0 for new freezing point.

For boiling point, mols is same, m is same, delta T = Kb*m

Add delta T to 100 for new b.p.
