While ethanol (CH,CH,OH) is produced naturally by fermentation, e.g. in beer- and wine-making, industrially it is synthesized by reacting ethylene (CH,CH,) with water vapor at elevated temperatures. A chemical engineer studying this reaction fills a 125 L tank with 52. mol of ethylene gas and 51. mol of water vapor. When the mixture has come to equilibrium he determines that it contains 33. mol of ethylene gas and 32. mol of water vapor. The engineer then adds another 17. 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. | mol
