Formula of Carbon monoxide (CO)
Identification of Carbon monoxide Chemical Compound
| Chemical Formula | CO |
|---|---|
| Molecular Weight | 28.0101 g/mol |
| IUPAC Name | carbon monoxide |

Chemical Formula Description
The carbon monoxide molecule contains a total of 2 atom(s). There are 1 Carbon atom(s) and 1 Oxygen atom(s). A chemical formula of carbon monoxide can therefore be written as:
CO
The chemical formula of carbon monoxide shown above is based on the molecular formula indicating the numbers of each type of atom in a molecule without structural information, which is different from the empirical formula which provides the numerical proportions of atoms of each type.
The above chemical formula is the basis of stoichiometry in chemical equations, i.e., the calculation of relative quantities of reactants and products in chemical reactions. The law of conservation of mass dictates that the quantity of each element given in the chemical formula does not change in a chemical reaction. Thus, each side of the chemical equation must represent the same quantity of any particular element based on the chemical formula.

Chemical structure of carbon monoxide
The chemical structure image of carbon monoxide is available in chemical structure page of carbon monoxide, which specifies the molecular geometry, i.e., the spatial arrangement of atoms in the chemical formula of carbon monoxide and the chemical bonds that hold the atoms together.
-
Molecular weight of carbon monoxide
The molecular weight of carbon monoxide is available in molecular weight page of carbon monoxide, which is calculated as the sum of the atomic weights of each constituent element multiplied by the number of atoms of that element specified in the chemical formula of carbon monoxide.
-
InChI (IUPAC International Chemical Identifier) information of carbon monoxide
The molecular chemical formulas lack structural information. An alternative textual expression including the structural information is InChI. The full standard InChI of carbon monoxide is:
InChI=1S/CO/c1-2
It can provide a standard way to encode the molecular information of carbon monoxide to facilitate the search for the compound information in databases and on the web.
The condensed, 27 character standard InChIKey (hashed version of the full standard InChI) of carbon monoxide is:
InChIKey=UGFAIRIUMAVXCW-UHFFFAOYSA-N
The InChIKey may allow easier web searches for carbon monoxide, but it needs to be linked to the full InChI to get back to the original structure of the carbon monoxide since the full standard InChI cannot be reconstructed from the InChIKey.
