Compound $X$ is made up only of the elements $\mathrm{C}$, $\mathrm{H}$ and $\mathrm{O}$. When $2.00\,\text{g}$ of $X$ is completely combusted, $4.00\,\text{g}$ of carbon dioxide and $1.63\,\text{g}$ of water are produced. What is the empirical formula of $X$?
- A$\mathrm{CHO}_2$
- B$\mathrm{C}_2\mathrm{H}_2\mathrm{O}$
- C$\mathrm{C}_2\mathrm{H}_4\mathrm{O}$
- D$\mathrm{CH}_2\mathrm{O}_2$
