7 g 235U is approx. equivalent to 20 t coal (for the complete fission of the uranium).
There are many types of uranium pellets depending on the nuclear reactor type and the used uranium enrichment (or uranium-235 content). It may be more illustrative to say that: 1 gram of uranium-235 when undergoes fission in a nuclear reactor gives energy roughly equivalent to burning 3 tonnes of coal or 2 tonnes of oil.
The mass of o,5 mole of uranium is 119,014455 g.
The vast majority of mass of uranium ore is U-238 and much of that is discarded as Depleted Uranium. U-235, assuming complete fission, would release about 80 billion joules per gram. Usually Enriched Uranium for reactors (reactor grade) is around 3-4% U-235, as opposed to Weapons Grade, which is much higher. The answer depends both on what you mean by a gram of uranium and the process for deriving the energy. If we're talking only about normal uranium ore, about 200 million joules per gram, a few thousand times that produced by burning gas, coal, etc. I'm basing that off the amount of uranium ore consumed for a 1000 megawatt Light Water Reactor, and is a very rough calculation, but you're going to get a wide range of values depending on the process and the individual make up of isotopes in the fuel rods. Your losing a lot of energy to waste heat, your not using most of the fuel all the way up, and so on. But a 1000 MW LWR consumes around 170 tons of uranium ore a year, so from a practical standpoint, if you're asking how much usable energy we get out of a gram of uranium, this is better value than the 80 billion joule value.
That's like asking how many cars can be powered by 1 gallon of gas ... it's going to depend on how long you want to keep it up. One house can be powered for a very long time, and a million houses can also be powered but not for so long.
Nuclear Energy generates a lot of energy rather than other Power Plants. One gram of uranium equals to 60 thousand tons of coal, and the energy it produce, so it is much more green (Despite the main disadvantage: explosion). The air is not as polluted as it would be with the coal. Because of the high levels of energy generation, energy cost is cheaper.
1 atom gram of natural uranium = 238,028 91 grams
Not normally. In fact I can not think of any pellet rifle that takes a 16 gram C02 cartridge.

1 atom-gram of uranium = 238,02891 grams
a gram of natural uranium having various isotopic makeups has a radioactivity of about .67 microCuries. One Curie is equal to the radioactivity possessed by a gram of radium.
Probably 0,1 USD for uranium in the unrefined oxide U3O8.
The monetary value of uranium is 10 dollars per gram and i dont give a ****
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.
Well, based on recent studies... In terms of power production, 1 kilogram of uranium-235 is equivalent to 2.7 million kilograms of coal. With those numbers in mind, I would expect 1 gram of uranium-237 to cost somewhere between $300-$600 million. There are many other factors involved but I do know that I need to be in the business of selling uranium because unemployment isn't paying my bills.

8 August 2011: 0,113 USD for 1 gram of the unrefinned oxide U3O8.
If you mean the standard 12 gram CO2 cartridges, they are not reusable.
