A 38.40 mg sample of an organic acid composed of just carbon,hydrogen, and oxygen was burned in pure oxygen to give 37.54 mg CO2and 7.684 mg H2O in a combustion analysis. In a separateexperiment, the molecular mass was determined to be 90. In atitration, 40.2 mg of the acid dissolved in 50 mL of water required14.28 mL of 0.0625 M NaOH for complete neutralization. Use thesedata to draw a reasonable Lewis structure for the compound.
Determine the empirical formula of the compound using thecombustion analysis data.
