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.
The answer depends on the compound.
It is 1:1 - the same number of atoms of Na and Cl.
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.
This ratio is 2/5.
This ratio is different for each compound; for the oxide P4O10 the ratio is 2/5.
The chemical formula of potassium nitride is K3N. The ratio potassium atoms/nitrogen atoms is 3.
The ratio of atoms in monosaccharides is 1 carbon: 2 hydrogen: 1 oxygen.
The ratio (as atoms) carbon/oxigen in graphitic oxides is between 2,1 and 2,9.
