While ethanol, CH3CH2OH, is produced naturally by fermentation, e.g. in beer- and wine-making, industrially it is synthesized by reacting ethylene, CH2CH2, with water vapor at elevated temperatures. A chemical engineer studying this reaction fills a 75 L tank with 12. mol of ethylene gas and 14. mol of water vapor. When the mixture has come to equilibrium he determines that it contains 3.9 mol of ethylene gas and 5.9mol of water vapor. The engineer then adds another 3.5 mol of water, and allows the mixture to come to equilibrium again. Calculate the moles of ethanol after equilibrium is reached the second time. Round your answer to 2 significant digits.
