| Cov pa roj carbon | C | 40.001% |
| Oxygen | O | 53.285% |
Qhov thib ob, ch3cooh yog dab tsi? CH3 COJ yog hu ua Acetic acid, tseem hu ua asethanoic acid thiab methane carboxylic acid, yog cov kua tsis muaj xim uas muaj zog thiab sib txawv pungent thiab qaub tsw. Nws muaj ob carbon (C) atoms, plaub hydrogen (H) atoms thiab ob oxygen (O) atoms. Vim nws muaj ib tug carbon nyob rau hauv nws cov tshuaj formula, nws yog ib tug organiccompound.
