Helium isn't usually sold by the gram, but by volume. Typical prices for a, say, 15 cubic foot container (that's 15 cubic feet at STP; the container itself is significantly smaller) would be around $50.
A cubic foot is about 28.3 L, so that's about $0.12 per liter. A mole of ideal gas at STP is 22.4 L, and a mole of helium would have a mass of 1 gram, so, roughly $2.70 per gram is about right.
As with most things, you can get a much better price if you buy in bulk.
It cost $5 per 100 grams
Francium is not a commercial product.
No. Helium is one of the "noble" gasses, and they generally don't react with much.
It costs about $27 million per gram.
I won't even waste the time looking up actual numbers.a mole of atoms of helium is about 4 grams, therefor 1 gram of helium is about 0.25 moles of helium atomsa mole of atoms of uranium is about 238 grams, therefor 1 gram of uranium is about 0.0042 moles of uranium atomsA gram of helium contains more atoms than a gram of uranium by about a factor of 60.
iridium costs about $450 troy ounce. The price of the metal fluctuates daily

idk but one gram is between 6-11 euro. Max purchase at one store is 5g.
