Ethane $($C$2$H$)$ burns completely with $230\%$ of theoretical air entering at $74$F$,1$ atm, $50\%$ relative humidity. The dry air component can be modeled as $21\%$ O$2$ and $79\%$ N$2$ on a molar basis. The combustion products leave at $1$ atm. Determine the mole fraction of water in the products, in Ibmol$($water$)/$Ibmol$($products$).$
