Glycerin, ethylene glycol and methanol are sold at the same price per kg. Which would be cheaper for preparing an antifreeze solution for the radiator of an automobile?
The antifreeze solution is responsible for lowering the freezing point of water so as to avoid the damage in the radiator in automobile system. Here, 3 solutes are needed to be compared i.e., glycerin, ethylene glycol and methanol. According the formula; ΔTf=KfmΔTf=Kfm where, m = molality and is stated as; m=W2/M2W1
