At $\displaystyle 300$ K and $\displaystyle 1$ atm, $\displaystyle 15$ mL of a gaseous hydrocarbon requires $\displaystyle 375$ mL air containing $\displaystyle 20 \% \mathrm{O}_2$ by volume for complete combustion. After combustion the gases occupy $\displaystyle 330$ mL . Assuming that the water formed is in liquid form and the volumes were measured at the same temperature and pressure, the formula of the hydrocarbon is :
