This compound is also known as Acetic Acid. The percentage by weight of any atom or group of atoms in a compound can be computed by dividing the total weight of the atom (or group of atoms) in the formula by the formula weight and multiplying by 100. For bulk stoichiometric calculations, we are usually determining molar mass, which may also be called standard atomic weight or average atomic mass. At STP, the melting and boiling points of ethanoic acid are 289K and 391K respectively. Use that to determine the molar mass. The mass of solute in the acid solution is relatively low, therefore the acid is dilute. Now, using your found molar amount of CH3COOH and … Molar mass acetic acid = 60.05 g/mol Weigh out 60.05 g acetic acid and add to a 1.000 L flask. The mass of one mole of a substance is its molecular mass in grams. The molar mass of acetic acid is 60 g/mol.
