It's the molecular weight divided by 22.4 L/moles. 6.52 g/L is the answer. The molecular weight is 146.05. That number is what one sulfur and six flourides equal.
SF6
add their masses together and you get 146g
146/ L x 22.4L/1 mol = 3270 g/L

The density of a gas is propotional to its molecular weight. Air is composed of primarily of nitrogen and oxygen, which have molecular weights of about 28 g/mol and 32 g/mol respectively. Sulfur hexafluoride has a molecular weight of about 146 g/mol, which would make it roughly 5 times denser than air.
SCl6 . this compound is not known. The compound SF6 sulfur hexafluoride is known- it is a gas under normal conditions.

That would be sulfur hexafluoride. It is a very useful gas, but it's also the most potent greenhouse gas there is.
Sulfur hexafluoride.
SF6 is sulphur-hexa-fluorine, it is used in gaseous form as an arc suppressent and also to insulated EHV busducts and switchgear.
Hydrogen gas has a very low density; 0,08988 g/L; uranium hexafluoride (as gas) is very dense, between gases.
The chemical formula of uranium hexafluoride is UF6.
The density of a gas is propotional to its molecular weight. Air is composed of primarily of nitrogen and oxygen, which have molecular weights of about 28 g/mol and 32 g/mol respectively. Sulfur hexafluoride has a molecular weight of about 146 g/mol, which would make it roughly 5 times denser than air.
Examples: tritium, sulfur tetrafluoride, tellurium hexafluoride, etc.
