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
Yes, chlorine gas is heavier than air. It has a higher density than air, causing it to stay near the ground when released. This characteristic makes chlorine gas particularly dangerous in enclosed or low-lying areas.
No. 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.
How much heavier than air is chlorine gas?
Chlorine gas is approximately 2.5 times heavier than air. This means that it tends to sink and accumulate in low-lying areas rather than dispersing upwards into the atmosphere.
How many times is chlorine gas heavier than air?
2.5 times
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.
What is the appearance of chlorine at room temperature?
Chlorine is a greenish-yellow gas at room temperature. It has a strong, pungent odor and is heavier than air.
Is a coloured poisonous gas fairly soluble in water and heavier than air?
Yes, a coloured poisonous gas that is fairly soluble in water will tend to dissolve in water when exposed to it. In addition, if the gas is heavier than air, it will tend to accumulate near the ground rather than disperse into the atmosphere.
Is natural gas heavier than air?
Yes, natural gas is lighter than air. It will rise and dissipate into the atmosphere if released into the air.
What kind of air is heavier than another type of air?
Gas is heavier than oxygen. Cold air is heavir than hot air
What gas is heavier?
Carbon dioxide (CO2) is heavier than air.
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.
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.
How do you identify chlorine gas?
Chlorine gas has a greenish-yellow color and a strong, pungent odor similar to bleach. It is heavier than air and may cause respiratory irritation or difficulty breathing when inhaled. Chemical detection devices can also be used to confirm the presence of chlorine gas.
Does a gas become heavier than air when it condenses into a liquid?
This depends on the gas.
