Assume 100g of the compound, 7.743 g H and 92.257 g O

**$\mathbf{7}\mathbf{.}\mathbf{743}\mathbf{}\overline{)\mathbf{g}\mathbf{}\mathbf{H}}\mathbf{}\mathbf{\times}\frac{\mathbf{1}\mathbf{}\mathbf{mol}\mathbf{}\mathbf{H}}{\mathbf{1}\mathbf{.}\mathbf{008}\mathbf{}\overline{)\mathbf{g}\mathbf{}\mathbf{H}}}$ = 7.68 mol H**

**$\mathbf{92}\mathbf{.}\mathbf{257}\mathbf{}\overline{)\mathbf{g}\mathbf{}\mathbf{C}}\mathbf{}\mathbf{\times}\mathbf{}\frac{\mathbf{1}\mathbf{}\mathbf{mol}\mathbf{}\mathbf{C}}{\mathbf{12}\mathbf{.}\mathbf{01}\mathbf{}\overline{)\mathbf{g}\mathbf{}\mathbf{C}}}$ = 7.68 mol C**

**$\frac{\mathbf{7}\mathbf{.}\mathbf{68}\mathbf{}\overline{)\mathbf{mol}}\mathbf{}\mathbf{H}}{\mathbf{7}\mathbf{.}\mathbf{68}\mathbf{}\overline{)\mathbf{mol}}}$ = 1 H**

**$\frac{\mathbf{7}\mathbf{.}\mathbf{68}\mathbf{}\overline{)\mathbf{mol}}\mathbf{}\mathbf{C}}{\mathbf{7}\mathbf{.}\mathbf{68}\mathbf{}\overline{)\mathbf{mol}}}$ = 1 C**

A compound composed of only carbon and hydrogen is 7.743% hydrogen by mass. Propose a Lewis structure for the lightest of the possible compounds.
