Both acids and bases contain a hydrogen atom.
In bases the hydrogen is covalently bound to an atom of oxygen to form a hydroxyl group (-OH), which binds ionicly through the oxygen atom to a cation or exists freely as OH(-) anion unbound in solution.
Hydrogen in an acid is a cation which binds ionicly with an anion or exists unbound in solution as the cation H(+). (actually as H3O(+))

while you're certainly asking for the form of atoms and not the form of molecules, then the above 2 answerers forgot to multiply via the form of atoms in step with molecule (CH3COONa has 8 atoms in all). a) Taking this into consideration. 14.5g * (a million mol / 82g) * 6.02*10^23 (molecules / mol) * (8 atoms / molecule) = 8.fifty two * 10^23 atoms b) same element: 14.5 mol * 6.02*10^23 (molecules/mol) * 8 (atoms/molecule) = 6.ninety 8 * 10^25 atoms

Acids contain H+ ions.
Bases contain -OH ions.
