ethylene, C2H4, has a mass of 28. air is about 20% oxygen, O2, with a mass of 32 and 80% nitrogen, N2, with a mass of 28. That makes it just lighter than air. , the same as oxygen gas.Ethylene has a density of less that 1 hence it is lighter than air.It is slightly lighter than air: Air at 15 C = 1.225 g/l Ethylene at 15 C = 1.178 g/l

∙ 12y agoNo. It is actually lighter than air.
You can work this out from the fact that a gas's density is proportional to its formula mass.
If we take the atomic masses of Carbon (C) as 12, Hydrogen (H) as 1, Oxygen (O) as 16 and Nitrogen (N) as 14 then:
Air contains Nitrogen (N2) - 78% and oxygen (O2) 21%. The equivalent 'formula mass' of air is therefore just slightly more than 28 (2 x14)
Methane's (CH4) formula mass is 12+ 4 or just 16 - so it is lighter than air as the formula mass (and hence density) is less than 28.
Carbon Dioxide (CO2) has a formula mass of 44 (12 + 16 + 16) so it is much more dense than air.
Hydrogen (H2) with a formula mass of just 2, is much lighter than air - in fact it is the lightest gas of all.

Is chlorine gas heavier then air and why?
Yes, chlorine gas is about 2.5 times heavier than air. At standard conditions (pressure = 101.325 kPa and tenmperature = 15 degC), the density of chlorine gas is 3.04 kg/m3 and the density of air in 1.202 kg/m3. This means that chlorine gas will not 'rise' and tend to stay low on the ground. This causes many problems with ventilation.
Are gasoline fumes heavier than air?
Bottled LPG is heavier than air That why it is recommended to place the gas bottle outside of the cabin. Any gas leaks from the bottle being inside, would collect in the bottom of the boat causing a very explosive mixture
Is bromine gas heavier than air?
The bromine vapors are heavier than air.
What characteristics of CFC make them more likely than most other chlorine compounds to reach the stratosphere?
CFC's are heavier than air and contain chlorine thus they would be part of the group of chemicals in question. In theory most items heavier than air should not be able to reach high altitudes, although very small amounts of this gas have been found in the stratosphere.CFCs are attracted to ultraviolet radiationthey are very stableWhich refrigerant is a chlorine-free refrigerant
What is chlorine's density?
Yes, chlorine is denser than air at the same p and T Density ratio is the same as 'mol' mass ratio 71 to 28.8 (g/mol), so about 2.5 times 'heavier'.
How much heavier than air is chlorine gas?
Chlorine is about 2.7 times denser than air.
How many times is chlorine gas heavier than air?
2.5 times
Is a coloured poisonous gas fairly soluble in water and heavier than air?
Its Chlorine

What kind of air is heavier than another type of air?
Gas is heavier than oxygen. Cold air is heavir than hot air
Is lpg gas is heaver than air?
Yes LPG in gas phase is heavier than Air.
Is natural gas lighter or heavier than air?
Natural gas is lighter than air and rises.
What is one major difference between sodium chloride and chlorine?
One is a solid and one is a gas! Sodium chloride is known as common salt and the oceans contain billions of tons of it. Chlorine is a green poisonous gas which is heavier than air.
Does a gas become heavier than air when it condenses into a liquid?
This depends on the gas.
