The molecular ion peak in a mass spectrum corresponds to the mass of the entire molecule. Therefore, the fact that compound X has a molecular ion peak at m/z 136 indicates that its molecular mass is 136. However, we cannot determine the molecular formula or empirical formula of the compound based on this information alone.
