Chemical formula with lowest terms
Web1. Based on their structures, rank phenol, benzene, benzaldehyde, and benzoic acid in terms of lowest to highest boiling point. Solution. By thinking about noncovalent intermolecular interactions, we can also predict relative melting points. All of the same principles apply: stronger intermolecular interactions result in a higher melting point. Web1.) Calculate the formula weight of acetic acid from its formula. 2.) Multiply the number of atoms of oxygen in the molecular formula by the atomic weight of oxygen and then divide by the formula weight of acetic acid. 3.) Multiply the answer by 100 percent to find the mass percentage of oxygen in acetic acid.
