A naqueoussolutioncontaining 288 gmofanon-volatilecompoundhavingthestoichiometriccomposition \( \mathrm{C}_{\mathrm{x}} \mathrm{H}_{2} \mathrm{O}_{\mathrm{x}} \) in 90 gm water boils at \( 101.24^{\circ} \mathrm{C} \) at \( 1.00 \) atmospheric pressure. What is the molecular formula?
\( \mathrm{P} \)
\[
\begin{array}{l}
\mathrm{K}_{\mathrm{b}}\left(\mathrm{H}_{2} \mathrm{O}\right)=0.512 \mathrm{~K} \mathrm{~mol}^{-1} \mathrm{~kg} \\
\mathrm{~T}_{\mathrm{b}}\left(\mathrm{H}_{2} \mathrm{O}\right)=100^{\circ} \mathrm{C}
\end{array}
