1.3 Elemental Composition of Pure Substances
A student completely combusts a \(2.90 \text{ g}\) sample of an unknown organic compound composed only of \(\text{C}\), \(\text{H}\), and \(\text{O}\) in an excess of \(\text{O}_2\text{(g)}\). The combustion produces \(6.60 \text{ g}\) of \(\text{CO}_2\text{(g)}\) and \(2.70 \text{ g}\) of \(\text{H}_2\text{O(g)}\). What is the empirical formula of the compound?
