Combustion of a \(0.1908 \mathrm{g}\) sample of a compound gave \(0.2895 \mathrm{g} \mathrm{CO}_{2}\) and \(0.1192 \mathrm{g} \mathrm{H}_{2} \mathrm{O} .\) Combustion of a second sample weighing \(0.1825 \mathrm{g}\) yielded \(40.2 \mathrm{mL}\) of \(\mathrm{N}_{2}(\mathrm{g}),\) collected over \(50 \% \mathrm{KOH}(\mathrm{aq})\) (vapor pressure \(=\) \(9 \mathrm{mmHg}\) ) at \(25^{\circ} \mathrm{C}\) and \(735 \mathrm{mm} \mathrm{Hg}\) barometric pressure. When \(1.082\mathrm{g}\) of compound was dissolved in \(26.00 \mathrm{g}\) benzene \(\left(\mathrm{mp} 5.50^{\circ} \mathrm{C}, K_{\mathrm{f}}=5.12^{\circ} \mathrm{C} m^{-1}\right),\) the solution had a freezing point of \(3.66^{\circ} \mathrm{C}\). What is the molecular formula of this compound?
