A student completely combusts a \(0.900 \text{ g}\) sample of a pure organic compound containing only \(\text{C}\), \(\text{H}\), and \(\text{O}\) in an excess of pure \(\text{O}_2\text{(g)}\). The reaction produces \(1.32 \text{ g}\) of \(\text{CO}_2\text{(g)}\) and \(0.540 \text{ g}\) of \(\text{H}_2\text{O(g)}\), which are collected quantitatively. Based on these data, what is the percent by mass of carbon in the original compound?
