1.3 Elemental Composition of Pure Substances
1.1 Moles and Molar Mass
A student analyzes a sample of a pure gaseous nitrogen oxide. Elemental analysis determines that the compound consists of \(30.4\%\text{ N}\) and \(69.6\%\text{ O}\) by mass. Mass spectrometry of the pure compound shows a molecular ion peak at \(m/z = 92.0\text{ u}\). Which of the following particulate diagrams best represents a sample of this gas containing a total of \(8\) empirical formula units?
