This ratio is different for each compound; for the oxide P4O10 the ratio is 2/5.
A chemical formula shows the elements in the compound and the ratio of atoms. For example, the chemicals formula for carbon dioxide is CO2 . In the carbon dioxide, there are always two oxygen atoms to every one carbon atom.
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 stoichiometry is governed by the laws of definite proportions and multiple proportions.
Such common compound is Glucose C6H12O6 but most of the mono saccharides have same ratio.
2:1 ratio. There would be eight atoms of hydrogen and four atoms of oxygen.

These ratios are not identical. In N2O5 the ratio is 2/5. In NO2 the ratio is 1/2.
A chemical formula shows the elements in the compound and the ratio of atoms. For example, the chemicals formula for carbon dioxide is CO2 . In the carbon dioxide, there are always two oxygen atoms to every one carbon atom.
A chemical compound that has a set number of atoms for each element. E.g. water H2O has the fixed ratio of 2:1, that is 2 hydrogen atoms to 1 oxygen atom, carbon dioxide CO2 has a fixed ratio of 1:2 (1 carbon atom to 2 oxygen atoms). It has to be fixed as if it isn't it makes a new compound/chemical.
Calcium oxide, CaO: the ratio is 1.
The answer depends on the compound.
