AP Chemistry
1.3 Elemental Composition of Pure Substances
1.1 Moles and Molar Mass
A \(0.890\text{ g}\) sample of a pure solid organic compound containing only \(\text{C}\), \(\text{H}\), \(\text{N}\), and \(\text{O}\) is completely combusted in an excess of pure \(\text{O}_2\text{(g)}\). The combustion products are directed through a series of selective traps, producing the data in the table below.
Based on these data, what is the empirical formula of the compound?
| Product Trap | Mass of Product Collected (\(\text{g}\)) |
|---|---|
| \(\text{CO}_2\text{(g)}\) absorber | \(1.320\) |
| \(\text{H}_2\text{O(g)}\) absorber | \(0.630\) |
| \(\text{N}_2\text{(g)}\) collection tube | \(0.140\) |
Based on these data, what is the empirical formula of the compound?
