A blend of ethanol and methanol is burned in oxygen, giving $35\,\text{cm}^3$ of $\text{CO}_2$ and $55\,\text{cm}^3$ of $\text{H}_2\text{O}$. The combustion is complete, and the volumes of both products are recorded at $101\,\text{kPa}$ and $120^\circ\text{C}$. What is the molar ratio, ethanol:methanol, in the mixture?
- A1:3
- B2:3
- C3:2
- D3:1
