The Data Booklet is needed for this question. $1.00\,\text{g}$ of carbon is burned in a restricted supply of pure oxygen. $0.50\,\text{g}$ of the carbon burns to make $\text{CO}_2$ and $0.50\,\text{g}$ of the carbon burns to make $\text{CO}$. This mixture of $\text{CO}_2$ and $\text{CO}$ is then passed through excess $\text{NaOH(aq)}$, after which the gas that remains is dried and collected. Calculate the volume of the remaining gas. (All gas volumes are measured at $25^\circ\text{C}$ and $1\,\text{atmosphere}$ pressure.)
- A$1\,\text{dm}^3$
- B$1.5\,\text{dm}^3$
- C$2\,\text{dm}^3$
- D$3\,\text{dm}^3$
