Gaseous butane (CH3(CH2)2CH3) reacts with gaseous oxygen gas (O2) to produce gaseous carbon dioxide (CO2) and gaseous water (H2O). If 19.4g of water is produced from the reaction of 55.22g of butane and of 114.6g oxygen gas, calculate the percent yield of water. Round your answer to 3 significant figures.
