There are 3 carbon atoms in a molecule of C3, as indicated by the subscript "3" following the element symbol C.
One, as indicated by the lack of an explicit subscript immediately following the symbol for carbon in the molecular formula.
As indicated by the subscript on the atomic symbol for oxygen, there are 3 oxygen atoms.
There are two sodium atoms in each molecule of Na2O, as indicated by the subscript immediately after the symbol for sodium atoms in the formula.
4, as indicated by the subscript on the symbol for hydrogen in the formula for methane, CH4.
Since each mole of carbon dioxide molecules contains two moles of oxygen atoms, as indicated by the formula CO2 for carbon dioxide, half a mole of carbon dioxide will have one mole of oxygen atoms.
The water molecule itself does not contain any atoms of carbon. Only two atoms of hydrogen and one atom of oxygen. However, many carbon compounds can be dissolved in water.
