During the monitoring of the catalytic oxidation of a hydrocarbon, a crystalline intermediate is isolated. Elemental analysis shows that this intermediate has the empirical formula C2H3O2\text{C}_2\text{H}_3\text{O}_2C2H3O2. A mass spectrum of the reaction mixture reveals that the molecular ion peak for this intermediate is at m/z=118.0m/z = 118.0m/z=118.0. What is the molecular formula of this intermediate?
Relative atomic masses (ArA_{\text{r}}Ar): C=12.0\text{C} = 12.0C=12.0, H=1.0\text{H} = 1.0H=1.0, O=16.0\text{O} = 16.0O=16.0.
