The density of uranium is 19 grams/cc, so 1000 grams will be 52.6 cc which is about 10 teaspoons.
If 1 teaspoon has a volume of 3,7 cm3 and the density of uranium is ca. 19,05 g/cm3 a teaspoon may contain ca. 70,5 g of uranium.
1 kg of uranium-235 is equivalent to 24.10ex.6 kWh.
Approx. 125 US $ for 1 kg of unrefined uranium oxide U3O8.
Probably approx. 40 kg of enriched uranium.
Cca. 50 kg of highly enriched uranium. Now nuclear bombs use plutonium, not uranium.
Uranium dioxide, nuclear grade, not enriched has a value greater 100 US $/kg.
Depending very much on the chemical or physical form, purity, enrichment, etc. For nuclear grade powder of natural uranium dioxide: ca. 100 $/kg.
Approx. 90 000 US $ for 1 000 kg of unrefined uranium octaoxide (U3O8).
Approx. 70 US $ for 1 kg of nuclear reactor grade uranium doxide (with natural uranium); the enriched uranium is more expensive, depending on enrichment.
approx. 120 US $ for 1 kg of unrefined uranium (exprimed as U3O8)
The price of 1 kg uranium octaoxide (U3O8) is approx. 90 US $/kg.
abundance of uranium in the earth crust; 2,5-3 ppm (mg/kg) abundance of uranium in the sea water: ca. 3 ppb (?g/kg)
