No. Nitrogen is slightly less dens than air. The density of a gas is directly proportional to its molecular mass. Dry air is 78% nitrogen, 21% oxygen. Nitrogen has a molecular mass of 28 AMU. Oxygen has a molecular mass of 32 AMU. This makes air just a bit denser than pure nitrogen.

Is there more nitrogen or carbon dioxide in the air?
There is more nitrogen in the air than carbon dioxide. Air contains:78.09% nitrogen20.95% oxygen0.93% argon0.03% carbon dioxideand trace amounts of other gases.
Why does air have more nitrogen than oxygen?
because it is light in weight there for occupy more space
What gas makes up 70 percent of the air?
Nitrogen gas (N2) makes up 79% of air (so more than 70%).
Is nitrogen denser than air?
No, air is more dense because it contains 20% oxygen, the heavier element than nitrogen (32 g/mol O2, i.s.o. 28 g/mol N2).
How the nitrogen is separated from air. what is the needed temperature for that?
You need to get the air liquid and then evaporate it - oxygen evaporates more easily than nitrogen. At normal pressure, air gets liquefied at about 78 kelvin (-195 degrees Celsius).
Is nitrogen in tires better?
Yes, nitrogen is more stable than air in tires.
What can you say about nitrogen?
it is inert, our air contains nitrogen more than any other gas
How many Time more nitrogen than oxygen make up air?
There is: Nitrogen (N2): 78.09% Oxygen (O2): 20.95% in the atmosphere There is ~3.73 times more oxygen than nitrogen in the air and is in a ratio (oxygen to nitrogen) of 39:10 (rounded).
What is true about air?
Good old air contains more Nitrogen than oxygen.
What happens when water vapor is lighter than nitrogen or oxygen?
Water vapor is a gas so it is in the air. Nitrogen and nitrogen are in the air too, but there is more nitrogen than anything in the air. I believe it rises because it is lighter, like a balloon filled with helium.
How much of the air is nitrogen?
The air is made up, mostly, of oxygen and nitrogen.. Air is 78 % nitrogen, 21 % oxygen, about 1 % argon, and a whole raft of other gases present in even smaller amounts..
Why percentage of nitrogen is very high in air?
Because that's how much there is, even if there were more oxygen in air than nitrogen this would be unhealthy!
How many times more than oxygen makes up air?
There is: Nitrogen (N2): 78.09% Oxygen (O2): 20.95% in the atmosphere There is ~3.73 times more oxygen than nitrogen in the air and is in a ratio (oxygen to nitrogen) of 39:10 (rounded).
How much more does warm air weigh than cold air?
a little
