glycol is used as an automobile antifreeze and in the manufacture of polyester fibers. The name of glycol stems from the sweet taste of this poisonous compound. Combustion of 6.38g of ethylene glycol gives 9.06mg CO2 and 5.5mg of H2O. The compound contains only C, H, and O. What are the percentage of the elements in ethylene glycol?
