In 2006, Professor Galen Suppes, from the University of Missouri-Columbia, was awarded a Presidential Green Challenge Award for his system of converting glycerin, a by-product of biodiesel production, to propylene glycol, Propylene glycol produced in this way will be cheap enough to replace the more toxic ethylene glycol that is the primary ingredient in automobile antifreeze. (a) If 50.0 mL of propylene glycol has a mass of 51.80 g, what is its density? (b) To obtain the same antifreeze protection requires 76 g of propylene glycol to replace each 62 g of ethylene glycol. Calculate the mass of propylene glycol required to re-place 1.00 gal of ethylene glycol. The density of ethylene glycol is 1.12 g/mL. (c) Calculate the volume of propylene glycol, in gallons, needed to produce the same antifreeze protection as 1.00 gallon of ethylene glycol.
