propane $($ C$3$H$8)$ burns completely with $190\%$ 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 combustiin products leave at $1$ atm. for complete combustion of propane with the theortical air $,$ what is the number of moles
