What is the molar mass of CO?

The molar mass of carbon monoxide or CO is 28.01 grams per mole. Scientists determine the molar mass of a compound by adding the atomic mass of each element contained in the molecule. The atomic mass of carbon is 12.01, and the atomic mass of oxygen is 16.

Carbon monoxide is an odorless, colorless gas that forms through the incomplete combustion of carbon compounds. This occurs when there is a limited amount of oxygen available. When exposed to heat in the presence of more oxygen, carbon monoxide burns with a blue flame. Carbon monoxide is poisonous to humans and animals because it binds to the hemoglobin cells in the blood, preventing them from transporting oxygen to the cells of the body.
