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 100L tank with 47. mol of ethylene gas and 41. mol of water vapor. When the mixture has come to equilibrium he determines that it contains 16. mol of ethylene gas and 10. mol of water vapor.

The engineer then adds another 16.mol of ethylene, 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.
