Liquid hexane CH3CH24CH3 reacts with gaseous oxygen gas O2 to produce gaseous carbon dioxide CO2 and gaseous water H2O. If 21.1g of carbon dioxide is produced from the reaction of 27.57g of hexane and 179.0g of oxygen gas, calculate the percent yield of carbon dioxide. Round your answer to 3 significant figures.
