Density of all gases are proportional only to their molar masses, because each mole of any gas takes a volume of 22.4 litre at standard temperature (0 oC), and pressure (1 bar).
Thus: from "formula => molar mass => density"
C2H2 => 2*12+2*1= 26 g/mol ==> density (at 0 oC, 1 bar) =26/22.4 =1.16 g/l
N2 => 2*14= 28 g/mol ==> density (at 0 oC, 1 bar) =28/22.4 =1.25 g/l
Nitrogen is a more dense gas than ethyn is.
Note: Ethene ( C2H4) is equal to nitrogen in density.
Acetylene is a gas at standard temperature and pressure.
The expansion ratio of acetylene is approximately 1:668 when it is converted from liquid to gas. This means that one volume of liquid acetylene will expand to form 668 volumes of acetylene gas at room temperature and pressure.
The density of acetylene gas at standard temperature and pressure (STP) is about 1.1707 kg/m^3.
The chemical change that produces acetylene gas is the reaction between calcium carbide (CaC2) and water. This reaction forms calcium hydroxide (Ca(OH)2) and acetylene gas (C2H2).
Acetic acid is a derivative of acetylene that is more acidic in nature. Acetylene is a hydrocarbon gas composed of two carbon atoms and two hydrogen atoms. Water, on the other hand, is a compound composed of two hydrogen atoms and one oxygen atom.
Because hydrogen gas is less dense than air(mostly nitrogen and oxygen), and the less dense gas flows to go above the more dense(and escape the atmosphere).
In the atmosphere it is a gas, in the soil it its a solid, nitrogen gas can be converted to liquid in air separation plants. Also, as a liquid Nitrogen is very cold -- cryogenic temperatures. Nitrogen is stored as liquid commonly for convenience, even when gas is required, because liquid is more dense than gas and more nitrogen could be stored in the same volume. Simply, the answer to your question is nitrogen is a solid, liquid and gas depending on where you find it or how you've modified it.
Many gases are filled in cylinders and include nitrogen, Carbon Dioxide, Helium, Hydrogen, Argon, Acetylene etc. Small cylinders that are extremely portable include butane etc.

Nitrogen Gas
Acetylene is a gas. It starts with the letter a.
The expansion ratio of acetylene is approximately 1:668 when it is converted from liquid to gas. This means that one volume of liquid acetylene will expand to form 668 volumes of acetylene gas at room temperature and pressure.
Nitrogen is four fifths of the air so their densities are very similar. Pure nitrogen is slightly less dense than air.
air is more dense than helium
Gas is not dense, solids should be dense, liquids are dense, but not as much as solids.
