1. An organic compound was found to contain 62.07% carbon, 10.34% hydrogen, and 27.59% oxygen. Determine its empirical formula and suggest a few possible molecular formulas. Name each of them. Do not consider ones that have more than 6 carbons.
2. A compound was found to have a molar mass of 245.8g and the following composition: 19.53% C, 2.44% H, 13.02%O, and 65.01% Br. Derive the empirical formula and its molecular formula.
3. A compound was found to contain 35.6% S, 11.1% H, and 53.3% C. Determine its empirical formula and suggest its molecular formula, knowing that it smells like rotten eggs when it becomes moist. Explain reasoning.
