All the gases is too much ! But some examples are:
Arsine AsH3 :3,29 g/dm3
Nitrogen dioxide NO2 :3,4 g/dm3
Carbon dioxide CO2 :1,87 g/dm3
Chlorine Cl :3,04 g/dm3
Fluorine F :1,59 g/dm3
The density of pure air is 1,2754 g/dm3 at standard pressure (100 kPa) and 0 0C.
i dont care.

Why do noble gases in balloon float in air?
Noble gases are lighter than air. Hence balloons filled with noble gases will float in air.
What determines if gases or vapors are lighter or heavier than air?
Their densities
Greenhouse gases are obviously lighter than air How then are they measured by weight How does one weigh something that is lighter than air?
Greenhouse gasses are NOT "obviously lighter than air"; carbon dioxide is significantly heavier than air.One way to weigh something that's lighter than air is to weigh it in a vacuum.
Are all noble gases lighter than air?
No. The molar mass of dry air is 28.97 g/mol. Noble gases are monatomic, so their atomic mass represent their molar mass. From this we can tell that helium and neon are less dense (lighter) than air, while argon (atomic mass 39.9) onwards are denser than air.
Is methane heavier than air?
All those gases which have molecular mass less than 28 are lighter than air as H2,He,CH4,and Ne.
When making a vortex using air do you want gases that are lighter or heavier than air?
Well, when I made a vortex using air, I used gases that are lighter.

Why do certain gases allow a balloon to rise?
Because the gases filling the balloon are lighter than the surrounding air.
Are all noble gases lighter than air?
No. The molar mass of dry air is 28.97 g/mol. Noble gases are monatomic, so their atomic mass represent their molar mass. From this we can tell that helium and neon are less dense (lighter) than air, while argon (atomic mass 39.9) onwards are denser than air.
Which gases weigh less than air?
Appended is a list of gases with their specific gravities. The specific gravity of a gas is a comparison of its density with that of air at the same temperature and pressure. Gases with a Specific Gravity (SG) less than1 are lighter than air.
What can gases do that solids cant?
They can take the shape of their container, and some are able to rise above air (some gases are lighter and some are heavier than room air.)
What keeps hot air balloons aloft?
the hot air inside the balloon is what's keeping the balloon aloft. the explanation is hot gases or air is lighter than cold air so hot air will rise since it is lighter than the cold air.
Is methane heavier than air?
All those gases which have molecular mass less than 28 are lighter than air as H2,He,CH4,and Ne.
What are lighter than air gases?
All of these 14 gases and no others are lighter than air at the same temperature and pressure. Neon Hydrogen fluoride Water (steam) Carbon monoxide Ammonia Nitrogen Hydrogen cyanide Methane Ethylene Acetylene Methllithium Diborane Helium Hydrogen
Is a blimp a type of hot air balloon?
No, it is a gas balloon. It relies on lighter than air gases (helium or hydrogen) to provide buoyancy.
