# What Is The Density Of Carbon Monoxide?

You might have heard of carbon monoxide. But, you may need to be made aware of the density of carbon monoxide. Carbon monoxide is denoted CO and it is a colorless, tasteless, odorless gas produced by burning gasoline, wood, charcoal, propane, and other fuel. Why is it called carbon monoxide? Because it has one atom of carbon and one atom of oxygen. When you see the chemical formula for carbon dioxide, it is CO2, which means it has two atoms of oxygen therefore they used the prefix ‘Di’. but here in CO, there is only one atom of oxygen, therefore they used the prefix ‘Mono’. Below we will discuss the density of carbon monoxide in detail, let’s get started.

## What Is The Density Of Carbon Monoxide?

The density of carbon monoxide is 1.14 kg/m3, which is at room temperature and standard pressure. Carbon monoxide is a drab, dull, and unscented combustible gas that is somewhat less thick than air. Therefore, when you see the density of carbon monoxide vs air, you will find that carbon monoxide is slightly less dense than air. You can measure the CO’s density in different units like

• The density of carbon monoxide g/ml is 1.145 g/ml
• The density of carbon monoxide g/cm3 is 11.40 g/cm3
• The density of carbon monoxide at STP is 1.14 kg/m3
• The density of carbon monoxide lb/ft3 is 2.436 lb/ft3
• The vapor density of carbon monoxide is 1.14 kg/m3

Carbon monoxide density depends upon the temperature and pressure. As pressure increases the density of CO decreases and as pressure decreases the density of CO increases. While as temperature increases, the density of CO increases and vice versa.

Now, you know what is the vapor density of carbon monoxide as well as the density of carbon monoxide gas. Let’s understand the definition of the density of carbon monoxide in detail.

## Definition Of Density Of Carbon Monoxide

The density of carbon monoxide is defined as the ratio of mass and volume. Or in other words, the density of carbon monoxide is the amount of carbon monoxide that can be occupied by a cubic centimeter of area or place. For any gas, to know its density, you need an equation called the Ideal Gas Law equation. The definition of the carbon monoxide density can be expressed in the equation form as,

Density of Carbon Monoxide = pressure constant x molar mass of Carbon Monoxide temperature x universal gas constant g/mL

Or

⍴ = PMRT g/mL

Here,

P = pressure = 1 atm

M = molar mass of Carbon Monoxide = 28 g mol-1

R = gas constant = 0.082057 L⋅atm/K⋅mol

T = temperature = 273.15 K

## How To Calculate Density Of Carbon Monoxide?

To calculate the density of carbon monoxide you should know the value of the mass and the volume of carbon as well as oxygen atoms. Ideally, there is an equation called Ideal Gas Law, which is used to measure the density of any gas. Above we have given you that equation and also the content values of carbon and oxygen. Let’s understand this equation by considering an example.

What is the density of carbon monoxide at standard temperature and pressure or STP?

By taking a formula,

Density of Carbon Monoxide = pressure constant x molar mass of Carbon Monoxide temperature x universal gas constant g/mL

Now, just putting the values of constant given above as,

⍴ = 1 atm × 28.014 g/mol0.082057 L⋅atm/K⋅mol ×273.15 K g/L

⍴  =  1.25 g/L

Hence, the density of CO at STP is  1.25 g/L.

## FAQ

### Is Co Heavier Or Lighter Than Air?

In fact, carbon monoxide is slightly lighter than air and diffuses evenly throughout the room.

### What Is The Density Of Carbon Monoxide Compared To Air?

The vapor density for carbon monoxide is 0.97, as referenced in Section 9: Physical and chemical properties of an applicable product safety data sheet. So, comparing CO’s vapor density of 0.97 to that of air (1), reveals that carbon monoxide is slightly lighter than air.

### Is Co Denser Than CO2?

Carbon dioxide is heavier than air and gas detectors should be put nearer the ground, whereas carbon monoxide is slightly lighter and detectors should be placed higher up.

### Does Carbon Monoxide Gas Rise Or Fall?

Carbon monoxide is lighter than air. It also rises with warm air, so the United States Environmental Protection Agency (EPA) recommends placing a carbon monoxide detector on a wall about five feet above the floor or about eye level. You can put them on the ceiling, too.

### Will Opening Windows Help With Carbon Monoxide?

Other Steps You Can Take

Be sure to read and follow the manufacturer’s instructions carefully. Still, leave the windows open a bit so there’s enough fresh air to dilute the carbon monoxide.

### Is Co Denser Than Oxygen?

CO2 is heavier than oxygen, so we might expect every CO2 molecule to sink below a layer of oxygen molecules.

### What Is The Density Of CO And CO2?

A mixture of CO and CO2 is found to have a density of 1.5g/litre at 30c and 730 torr.

## Conclusion

Carbon monoxide is currently a topic of conversation because the government of each and every country is trying to reduce carbon emissions. And in carbon emission, Carbon Monoxide is at the top because it is a byproduct of the combustion of all fuels. So, to reduce the emission of carbon monoxide, governments are trying to replace all fuel automobiles with electric or solar automobiles. Carbon monoxide is a harmful gas and carbon monoxide poisoning symptoms are dizziness, headache, weakness, upset stomach, vomiting, chest pain, and confusion. Therefore, always use a mask when you go to highly polluted areas. This was all about the density of carbon monoxide.
