Carbon Monoxide formula
Carbon Monoxide has one carbon atom bonded to one oxygen atom. It has the chemical formula of CO.
Physical properties of Carbon Monoxide
Appearance: Carbon Monoxide is a colorless gas.
Odor: It is an odorless gas, which makes it very dangerous because one will never know if they are being exposed.
Density: The density of this gas is about 1.25 kg/m³ at STP. It is lighter than air; it is approximately 0.97 times the density of air.
Solubility: Carbon Monoxide is very slightly soluble in water. Its water solubility can be determined as approximately 0.3 g/L at 20°C.
Boiling Point: The boiling point of carbon monoxide is −191.5°C.
Melting Point: The melting point of carbon monoxide is −205.1°C.
Molecular Weight: The molecular weight of carbon monoxide is approximately 28.01 g/mol.
Vapor Pressure: If carbon monoxide is found at its boiling point, then the vapor pressure of this compound is high. Generally, this will describe the nature of this compound as being observed as a gas at standard conditions.
Flammability: Carbon monoxide is highly flammable, forming explosive mixtures with air. The flammability limits of carbon monoxide in air are from 12.5 to 74% by volume.
