Any real-world consideration must take in to account the moisture in the air. Assuming 50% relative humidity at about 70 degrees F, the molecular weight of air would be about 28.01 which is almost exactly the same as the molecular weight of CO. In trying to figure out whether CO will rise to the ceiling or settle to the floor, the relative temperatures of the CO / Air would have to be considered. Information from the Canada Mortgage and Housing Corporation indicates: "Most manufacturers specify where you should locate their CO detector. In general, the best place to put the detector is where you will hear it while sleeping. CO is roughly the same weight as air and distributes evenly throughout a room, so a detector can be placed at any height in any location, as long as its alarm can be heard. Additional units could be installed in several other locations around the home, such as a child's bedroom; check the list below before installing. To avoid both damage to the unit and to reduce false alarms, do not install CO detectors: * in unheated basements, attics or garages * in areas of high humidity * where they will be exposed to chemical solvents or cleaners, including hair spray, deodorant sprays, etc. * near vents, flues or chimneys * within 2 metres (6 ft.) of heating and cooking appliances * near forced-or unforced-air ventilation openings * within 2 metres (6 ft.) of corners or areas where natural air circulation is low * where they can be damaged, such as an outlet in a high traffic area * where directly exposed to the weather."

Air is lighter than carbon monoxide. At standard conditions, the molecular weight of carbon monoxide (CO) is 28 g/mol, while the molecular weight of air is around 29 g/mol. This means that carbon monoxide is slightly heavier than air.

No, as it contains oxygen and carbon. Carbon monoxide contains 1 oxygen (mono) and 1 carbon.

Which is heavier carbon monoxide or oxygen?

Oxygen is heavier than carbon monoxide. The molecular weight of oxygen is 32 g/mol, while the molecular weight of carbon monoxide is 28 g/mol.


Is it bad if carbon monoxide is lighter than air?

No


If carbon monoxide is heavier than oxygen then why install carbon monoxide detectors on ceilings?

While carbon monoxide is slightly lighter than air, it diffuses evenly in a space and can reach lethal concentrations throughout a room, including at ceiling height. Installing detectors on ceilings ensures that they can effectively sense any buildup of carbon monoxide in the environment.


Is air lighter than carbon monoxide?

CO is lighter than airAt 25 degrees Celsius and 1 atm of pressure, carbon monoxide's density is 1.145kg/m3, and the density of air is 1.1839kg/m3. So carbon monoxide is slightly lighter than air.


Which element is heavier than carbon but lighter than oxygen?

The element that is heavier than carbon but lighter than oxygen is nitrogen. It has an atomic number of 7 and is located between carbon and oxygen on the periodic table.


Is carbon dioxide lighter than oxygen?

The molecular weight of carbon dioxide is heavier than oxygen. Oxygen has a molecular weight of 32 g/mol, while carbon dioxide has a molecular weight of 44 g/mol. Therefore, carbon dioxide is heavier than oxygen.


How many times heavier is helium than carbon?

Helium is a gas and is far more lighter than carbon which is a solid.


Is carbon monoxide heavier than air?

Yes, carbon monoxide is slightly lighter than air. It has a molar mass of 28.01 g/mol, which is less than the average molar mass of air (about 29 g/mol). This causes it to rise and distribute evenly in the atmosphere.


Is water lighter than carbon disulphide?

no,it is heavier than water and so it'll sink


Is carbon dioxide lighter than helium?

No, carbon dioxide is heavier than helium. Carbon dioxide has a molecular weight of about 44 g/mol, while helium has a molecular weight of 4 g/mol. This means that helium is lighter than carbon dioxide and will rise above it in the presence of air.


Does carbon monoxide diffuse faster than oxygen?

No, oxygen diffuses faster than carbon monoxide. This is because oxygen molecules are smaller and lighter compared to carbon monoxide molecules, allowing them to move more quickly through a membrane or barrier.


What are the disadvantages of carbon monoxide?

Frequently created by the incomplete burning of fuel, it consists of carbon and oygen. It is flammable, and lighter than air. It combines with red blood cells better than oxygen- making it difficult to get it out of your body once it is breathed in.Carbon monoxide (CO) is (3 main facts):an odorless,very toxicgas
