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.

cubic centimetres in a cubic metre = 10^6 = 1,000,000
19.05 x 1,000,000 = 19.05 million grams
19.05 million grams = 19,050 kilograms = 19.05 metric tons = Mass

How much is the energy output of one uranium pellet?
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.
Description of uranium?
Uranium is a silvery-white metallic element. It is ductile and slightly softer than steel. It has high density, about 70% more than lead, but slightly less than gold. It is radioactive, and slowly decays by alpha decay, though it occasionally spontaneously fissions under the influence of neutrons. In the presence of air, it quickly corrodes and develops a black oxide coating. In nature, it is always found in conjunction with other elements. One of the isotopes, Uranium-235, under the right conditions, can setup a nuclear chain reaction where neutrons split the Uranium-235, producing other nuclides along with more neutrons along with a large amount of energy. This can be controlled, such as in a power plant, or it can be uncontrolled, such as in a weapon.
What atom is used for nuclear power?
It was not a specific sort of atom. They split the atom.Not only is it a specific atom (element), it is a specific isotope of that element: Uranium-235. This is the one and only naturally occurring isotope that fissions and supports a chain reaction.
What is the critical mass of uranium-238?
Each isotope has a different critical mass. U235 is used because the mass needed to cause a reaction is smaller than almost all other isotopes. This critical mass is calculated as( 3.001 x 9.987 to the 11th power) Divided by the weight of one nuclei X 2.5675 (x 10 to the 24th power) divided by mass. This equals 7.702 X 10 to the 13th power divided by mass. You can tell by this calculation that critical mass for u235 is very low at about 1.3 kg. Best regards, Bruce
What is one example of a non solar nuclear energy?
Mechanical energy, solar energy, electrical energy. There are many more.
How many electrons does a atomic weight 235?
Uranium 235 has several isotopes but, 235 would contain 235 electrons in one atom.
Are uranium 235 and uranium 238 said to be radioactive molecules since they have the same number of protons but different numbers of neutrons?
No, Uranium-235 and uranium-238 are radioactive, natural isotopes (not molecules, but atoms) of the one and the same element: uranium.Both with 92 protons and 235-92 = 143 neutrons in U-235 but 146 neutrons in U-238.
Which uranium isotope is onley 0.7 percent of natural uranium and is the fissile part?
Uranium 235 is 0.7 percent of natural uranium and is fissile
What is the amount uranium is used in nuclear fission?
Minimum one atom of uranium 235.
What kind of uranium did Oak Ridge produce in World War 2 to bomb the Japanese?
Oak Ridge was built to separate Uranium 235 from Uranium 238. Uranium 235 is the fissile isotope of natural Uranium, suitable for use in bombs or power generation. 99+% of Uranium is U 238 and U 235 is less than one per cent.
One commonly used in nuclear power plants?
Uranium-235
Which is more explosive uranium-238 or uranium-235?
235 was used to produce one of the first atomic weapons. 238 is much harder to start a nuclear chain reaction than 235. 238 is used in nuclear weapons, but not as the first stage.
One way of showing the difference between isotopes of an element is to put the mass where?
Examples for the natural fissile uranium isotope: 1. Recommended notation: 23592U; 235 is the mass, 92 is the atomic number. 2. Alternative notation: U-235 or uranium-235.
What is the U-235 content of depleted uranium (DU)?
Depleted uranium is uranium with a content of the isotope uranium-235 under 0.7 %. Natural uranium has been processed to change (increase) the concentrations of lighter isotopes, and the "leftovers" are termed depleted uranium. Let's look at this heavy metal and sort things out. Without splitting hairs, the element uranium as it comes out of the ground is almost 99.27% U-238, and about 0.73% U-235. There's also a trace of U-234 in it. The isotope U-235 is the desired one for use in nuclear fuels and in nuclear weapons. Uranium is processed or "enriched" to increase the amount of the lighter isotope in the the finished product. This leaves the rest of the uranium "depleted" of some (or much) of its U-235 (and U-234, for what it's worth). The term depleted uranium is then applied to the remaining uranium. A link can be found below to check facts and gather more information.
When does Uranium-235 become unstable?
Uranium 235 is unstable because it is a radioactive isotope. This means that it is constantly decaying and emitting radiation. The reason it is unstable is because it has too many neutrons in its nucleus. The neutron is a unstable particle, and when there are too many of them in one place, they can cause problems. When uranium 235 decays, it emits alpha particles, which are high-energy particles that can damage DNA and cause cancer.
How much energy does one pound of uranium produce compare to petroleum?
1 pound of uranium 235 is approx. similar to 106 pounds of petrol.
How much matter is in uranium?
In one mole of Uranium there are 238.02891g of Uranium. This number comes from its atomic weight on the Periodic Table. The mass of one mole of an element is its atomic weight in grams.
