C to O in the ratio 1 : 2.
The ratio of atoms in monosaccharides is 1 carbon: 2 hydrogen: 1 oxygen.
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 answer depends on the compound.
It is 1:1 - the same number of atoms of Na and Cl.
There are two atoms of oxygen in the molecule. One of carbon and two of oxygen to get CO2.
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.
That is easy to determine by breaking it down. C = Carbon, O = oxygen, and the 2 says that there are 2 of the element that comes before it. So CO2 is 1 Carbon atom attached to 2 Oxygen atoms.
It is 1 carbon atom to every two oxygen atoms. I'm no maths whizz, but if carbon dioxide is CO2, then that must be it.
2 atoms
This ratio is 2/5.
1 mole of CO2 has 1 mole of carbon atoms and 2 moles of oxygen atoms. So, 0.000831 mole of CO2 will have 0.000831 mole of carbon atoms.
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.
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.
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.
Three atoms. Carbon dioxide is CO2
