Ken asks…How many liters of antifreeze ethylene glycol would you add to a car radiator containing 7.50?L of water if the coldest temperature in your area is -20.0 degrees celsius. (density is 1.11 g/mL).
what is the volume of antifreeze?Nancy answers:The optimal mix of water to antifreeze is 1:1 by volume. So I would use 3.75 l. H2O and 3.75 l. Ethylene glycol, this is because of the way antifreeze is manufactured - the minimum freezing point is at 70% e.g. By weight.
