The formula COS describes a molecule made of 1 carbon atom, 1 oxygen atom and 1 sulfur atom. It is written in Hill notation: carbon first, then hydrogen, then the other elements in alphabetical order. The formula tells you which atoms are present, not how they are connected, which is why several different chemicals can share it.

Frequently asked questions
What is the molar mass of COS?
The molar mass of COS is 60.07 g/mol, calculated from standard atomic weights for 1 carbon atom, 1 oxygen atom and 1 sulfur atom. The monoisotopic mass is 62.9746 Da.
How many compounds have the formula COS?
CompoundList lists 4 compounds with the molecular formula COS, including Carbonyl sulfide, Carbonyl-13C sulfide, Sulfanylidene(~13~C)methan(~18~O)one. Compounds that share a formula are isomers. They contain the same atoms arranged differently, so their properties, uses and prices can be very different.
What is the degree of unsaturation of COS?
COS has a degree of unsaturation of 2. That is the total number of rings and pi bonds (a double bond counts as one, a triple bond as two) in any structure with this formula.
