Please help, due in one hour I only need the number of atoms of each element

Sodium sesquicarbonate

Sodium carbonate, Na2CO3, (also known as washing soda, soda ash and soda crystals) is the inorganic compound with the formula Na2CO3 and its various hydrates. All forms are white, water-soluble salts that yield moderately alkaline solutions in water. Is surrounded roughly tetrahedrally by four atoms, two sodiums and two oxygens. As commonly observed in hydrate structures, the water oxygen is surrounded in this way by two cations and two anions, and in this matter sodium sesquicarbonate obeys the usual rule.

Sodium (Na), chemical element of the alkali metal group (Group 1 [Ia]) of the periodic table. Sodium is a very soft silvery-white metal.

Sodium is a chemical element with the symbol Na (from Latin "natrium") and atomic number 11. It is a soft, silvery-white, highly reactive metal. Sodium is an alkali metal, being in group 1 of the periodic table. Its only stable isotope is 23Na.

The common name for the chemical compound with the formula 3H2O is water. The H2O part is the formula for water. The 3 means that there are 3 molecules of water.

3H2O has 6 hydrogen atoms and 3 oxygen atoms.

Carbon monoxide (Co)        

Carbon monoxide is a colorless, odorless gas. Prolonged exposure to carbon monoxide rich atmospheres may be fatal. It is easily ignited. It is just lighter than air and a flame can flash back to the source of leak very easily. Under prolonged exposure to fire or intense heat the containers may violently rupture and rocket.

Carbon monoxide is a colorless, odorless, tasteless gas. A molecule of carbon monoxide (CO) contains one carbon atom and one oxygen atom.

Iron oxide or ferric oxide is the inorganic compound with the formula Fe2O3. It is one of the three main oxides of iron, the other two being iron(II) oxide (FeO) the rarer form, and iron(II,III) oxide (Fe3O4) which naturally as magnetite.  Since atoms are not divisible into halves, we should instead say that in the ferric molecule there are 3 oxygen atoms for every 2 iron atoms. Thus, (Fe is the symbol for an iron atom, and O is the symbol for an oxygen atom) the ferrous oxide molecule is FeO, and the ferric oxide molecule is Fe2O3.

Aluminium hydroxide, Al(OH)₃, is found in nature as the mineral gibbsite and its three much rarer polymorphs: bayerite, doyleite, and nordstrandite. Aluminium hydroxide is amphoteric in nature, i.e., it has both basic and acidic properties. 1 atom.
