4. An unknown organic acid contains only carbon, hydrogen, and oxygen. Use the combustion analysis data below to determine the empirical formula for the unknown organic acid Mass of unknown organic acid combusted :403 mg
Mass of CO2 recovered: 845
Mass of H2O recovered :173 mg
250.0 mg of the same unknown organic acid is used in a titration, where 7.51 mL of 0.198 M NaOH were needed to reach the equivalence point. Determine the molar mass, and molecular formula, of the unknown organic acid (the acid has 1 acidic proton, and a 1:1 stoichiometry with NaOH)
Answer: 168.12 g/mole, C8H8O4

An organic compound X was found to contain only C, H, and Cl. The following experiments were carried out with compound X: 1) When a 1.50-g sample of the compound was completely combusted in air, 3.52 g CO2 was formed. 2) When a 1.00-g sample of the compound was allowed to react with an excess of Ag, 1.27 g of AgCl was obtained. Determine the empirical formula of compound X. A0.258-g sample of a pure triprotic acid,...
