The answer depends on the compound.
The chemical formula of the compound shows the ratio of the atoms of elements in a compound. This must not be confused with the ratio of their masses.
A chemical formula gives the number ratio of the different kinds of atoms present in the compound. This means that the ratios are the same if you count in individual atoms, dozens of atoms, or molecules of atoms.
The ratio of atoms in monosaccharides is 1 carbon: 2 hydrogen: 1 oxygen.
C to O in the ratio 1 : 2.
They are called "formulas" (Latin formulae) and show what elements and ions are in the compound. The formula H2O for water shows that a water molecule is made of two atoms of hydrogen and one of oxygen.The symbols representing chemical compounds are called chemical formulas. They can be expressed as an empirical formulawhich shows the simplest ratio of atoms in the compound, or a molecular formula which shows the actual number of each atom in the compound, or as a structural formula which shows the spatial relationship of the atoms.
This ratio is different for each compound; for the oxide P4O10 the ratio is 2/5.
3 of the compound
This ratio is 2/5.
The ratio of different atoms in a compound important because the compound has to achieve an equilibrium in terms of electrical charge. The net total of charges of the atoms forming a compound must be zero.
The chemical formula of the compound shows the ratio of the atoms of elements in a compound. This must not be confused with the ratio of their masses.
A chemical formula shows what elements a compound contains, and the ratio of the atoms or ions of the elements in the compound.

These ratios are not identical. In N2O5 the ratio is 2/5. In NO2 the ratio is 1/2.
The ratio Na/Cl is 1 in the formula unit.
