How many liters of the antifreeze ethylene glycol [CH2(OH)CH2(OH)] would you add to a car radiator containing 6.50 L of water if the coldest winter temperature in your area is -28°C? (The density of ethylene glycol is 1.11 g/mL. Assume the density of water at -28°C is 1.00 g/mL.) Calculate the boiling point of this water-ethylene glycol mixture.
