The density of nitrogen is 1,2504 g/L.
The density of air is 1,2922 g/L.
Both values are at 20 oC.
Density of (dry) air at 25 degrees celsius: 1.225 kg/m^3 Density of nitrogen at 25 degrees celsius: 1.2506 kg/m^3
Oxygen is a light weight gas that makes up most of common air and is breathable, argon by it's density is not breathable and can cause suffocation by settling in the lower parts of the lungs and keeps oxygen from entering.
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.
Our air is about 79% Nitrogen.
Air is 78% Nitrogen
No, because people can only breathe with Earth air (which mainly consists of Nitrogen and Oxygen), and moon atmosphere has no Nitrogen or Oxygen.
what! no the only breathable air for humans is on Earth.

Yes, it is true because the density of oxygen is higher than the density of nitrogen.
Compared to liquids and solids, yes a very low density.
If you are asking whether nitrogen is less dense than air and will float on top of it, then yes, nitrogen is "lighter," albeit only slightly. More accurately, nitrogen, which is a constituent gas of air, is less dense than air, not lighter. The density of air at standard temperature and pressure is 1.292 kg/m3. The density of nitrogen is 1.251 kg/m3.
the higher you are the more the density decreases

It is breathable

Air is a mixture. Air is breathable, transparent, necessary for human life, and generally a good thing to have. Even when we travel into outer space, we take air with us.
Cotton is a breathable material. The atmosphere of Mars is not breathable by humans, yet.
