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

LaoNo. 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.
No it is not, cause the chlorine in gas is actually condesed, therefore air is heavier

Is chlorine gas heavier then air and why?
Yes, chlorine gas is heavier than air. This is because chlorine gas has a higher molecular weight compared to the average molecular weight of air, which is predominantly made up of nitrogen and oxygen. As a result, chlorine gas tends to settle closer to the ground rather than rise up.
Is bromine gas heavier than air?
Yes, bromine gas is heavier than air. It is about 7 times denser than air, so it will tend to sink and accumulate in low-lying areas. This makes it important to handle bromine gas with caution to avoid inhalation.
Chlorine gas and oxygen which is heavy?
Chlorine gas is heavier than oxygen. Chlorine gas has a molar mass of 70.9 g/mol, while oxygen has a molar mass of 32 g/mol. This difference in molar mass causes chlorine gas to be heavier and therefore it will tend to sink below oxygen in a mixture.
Are gasoline fumes heavier than air?
Gasoline fumes are generally lighter than air due to their lower density. This means they tend to rise and disperse rather than sink to the ground. However, it's important to note that gasoline vapors are still flammable and can pose a fire hazard if not handled properly.
Is chlorine less dense than air?
Yes, chlorine gas is less dense than air. Chlorine has a density of about 3.2 g/L, while air has a density of about 1.2 g/L. This difference in density explains why chlorine gas will tend to rise in air.
