Xenon Gas Pricing and Safety Concerns

[CognitiveNet]

One company is selling 1000 liters of Xenon gas for 8000 USD.
But other websites are stating that Xenon cost 120 USD per 100 grams.
And Xenon weight 5 grams per liter at 101300 Kpa.
I need to know how much 82Kg of Xenon would cost, or 50 liters at 150Kpa.

The price depends strongly on the purity, I think, since Xenon takes some effort to separate from Krypton.

BTW: In addition to making lead balloons, Xenon gas is useful for parlor tricks, since breathing it has the opposite effect to breathing Helium.

SF6 has about the same molar mass. Wish I could get some for use in classroom demos, but the economics seem impossible unless you have a lab that's really consuming it steadily.

Cool videos with SF6:

Note: inhaling helium is much safer than inhaling heavy gases - they tend to stick in the lungs and block air access. Simplest way of removing them is to stand on your head.
