delta T = Kf*m
Find mols:
mols = grams ethyl/molar mass = ?
Find molality:
m = molality = mols/kg solvent
Plug m and Kf(1.86) into the delta T formula and solve for delta T. Then subtract that from zero to find the new freezing point.
An antifreeze solution is prepared containing 40.0 g of ethylene glycol (molar mass = 62.0 g/mol) in 60.0 g of water. Calculate the freezing point of this
