How many moles are in a 140 grams of uranium?
divide 140 by the atomic weight of the uranium you want to know about. it will be different if you are asking about natural, enriched, or depleted uranium and how much its enriched or depleted.
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.
How much one uranium cost?
Approx. 99 US $ for 1 kg of unrefined oxide U3O8 (spot price at 30.07.2012).
How much does a kilogram of uranium cost?
approx. 120 US $ for 1 kg of unrefined uranium (exprimed as U3O8)
How much does depleted uranium cost per ounce?
I have been able to buy it for about $285 per ounce.
How much does it cost to buy uranium?
Approx. 125 US $ for 1 kg of unrefined uranium oxide U3O8.
How much uranium is used in a 10 kiloton fission bomb?
Probably approx. 40 kg of enriched uranium.
How much coal uranium and oil does South Africa have?
South Africa production: - uranium: approx. 1 000 t/year - coal: approx. 200.106 t/year - oil: approx. 200.103 barrels/day
Why does Australia have so much uranium and how much exactly is there?
The known reserves uf uranium in Australia are now approx. 1 700 00o t.
How much uranium does the us use each day?
approx. 70 tonnes.
How much does uranium cost by ton?
Approx. 90 000 US $ for 1 000 kg of unrefined uranium octaoxide (U3O8).
The primary health threat of depleted uranium is from its toxicity?
Yes, that is correct. Depleted uranium is a toxic metal and there have been studies made to show its ill effects. There is a much smaller secondary concern of radiation (as this material is still radioactive but much less so than natural or enriched uranium as it lacks the highly unstable isotope U-235) but toxicity is the primary threat.
