Helen asks…Chemistry problem?How many litres of the antifreeze ethylene glycol would you add to a car radiator containing 6.50 L of water if the coldest winter temperature in your area is -20 degrees Celsius? Calculate the boiling point of this water ethylene glycol mixture. The density of ethylene glycol is 1.11 g/ml.Nancy answers:20 = kf x m
20 = 1.86 x m
m = 10.8 = moles glycol / Kg water
Denity water = 1.0 g/mL
6.50 L=> 6.50 Kg
Moles glycol = 10.8 x 6.50 = 70.2
Mass ethylene glycol =
