All gases are denser except those with a 'lower than 28.8 molar mass', so from molar mass of N2 downwards to smaller molecules (nitrogen -28-, ethene -28-, ethyne -26- neon -20-, hydrogen fluoride-20-, water -18-, ammonia -17-, methane -16-, helium -4- and hydrogen -2-) which are lighter.

Is there more nitrogen or carbon dioxide in earth's atmosphere?
There is much more nitrogen in earth's atmosphere than carbon dioxide. Nitrogen forms about 79%, while carbon dioxide makes up about 0.04%.
Does the atmosphere store more carbon dioxide than the ocean?
No it does not
How many times more carbon is in the oceans than in the atmosphere?
The oceans contain about 50 times more carbon dioxide (CO2) than the atmosphere and 19 times more than the land biosphere.
Why does your body make more carbon dioxide when you run than when you sit down?
Carbon dioxide is the end product of the oxidation of carbohydrates, fats, etc., ie food. When you are using your muscles you are using more energy so you turn more "food" into carbon dioxide, which leaves your body through your lungs.
Why does the body give out more carbon dioxide than it has inhaled?
A living organism produces carbon dioxide from the sugars in food and the oxygen inhales with the air it breathes. This process creates the enery for body heat. processes and mvement. The carbon dioxide is taken to the lungs by the blood and exhaled.
Is carbon dioxide dense or more dense than air?
Carbon Dioxide is less denser than air.
Is carbon dioxide than air?
Carbon dioxide is more dense than air.
What two gases are more dense than carbon dioxide?
There are many gases more intrinsically dense than carbon dioxide, the most common being the gaseous element chlorine, the compound sulfur dioxide, and water vapor. Many gaseous organic chemicals such as butane and propane are more dense than carbon dioxide.
Is carbon dioxide more dense then air?
Carbon dioxide is approximately 50 percent heavier than air
Is Carbon dioxide more dense than water?
The density of a gas is directly propotional to its molecular mass. The main components of air are diatomic nitrogen and oxygen, which have molecular masses off approximately 28 AMU (atomic mass units) and 32 AMU respectively. Carbon dioxide has a molecular mass of approximately 44 AMU.
Does carbon dioxide has high or lower density than air?
Carbon dioxide is more dense than air.
Is water or carbon dioxide denser?
At room temperature and pressure, water is more dense than CO2. If CO2 is cooled and compressed to a liquid, it is more dense than water.
Does Venus have an atmoshpere?
Yes, an incredibly dense one. Mainly of carbon dioxide it is about 90 time more dense than the Earths atmosphere.
What is more dense than carbon dioxide?
Among gases, several are more intrinsically dense than carbon dioxide, including the gaseous elements chlorine and radon, the compounds sulfur dioxide and water vapor, and gaseous organic chemicals such as butane and propane.
Does warm carbon dioxide rise faster than cold carbon dioxide?
In an atmosphere of carbon dioxide, warm carbon dioxide would rise. Since carbon dioxide is better than twice as dense as air, it would need to be really hot before it would rise.
Is carbon dioxide less dense than the surrounding gasses in a room?
Air consists mostly of Nitrogen. Nitrogen's Molar Mass is 14.01. Carbon Dioxide's Molar Mass is 44.01. Therefore CO2 is more dense that Air (surrounding gasses)
Why is carbon dioxide more dense than air?
Air is a mixture of several different elements and compounds. Some (most, on average) are lighter or less dense than CO2, while some are heavier or more dense than CO2. The density of CO2 is 1.977 g/L, while the average density of air is 1.2 g/L.
