Is the density of hydrogen gas lower than that of uranium hexafluoride gas?
Yes, the density of hydrogen gas is lower than that of uranium hexafluoride gas. Hydrogen gas is one of the lightest elements, while uranium hexafluoride gas is much denser due to the heavy uranium atom.
How much is 1 molecule of uranium atoms?
Each isotope of an element has a different number of neutrons. Number of neutrons = Atomic mass of an isotope - atomic number of the element For uranium the atomic number is 92; for the isotopes see the list of isotopes with their atomic mass.
What is the mass number for the element uranium?
The atomic weight of uranium is 238,02891(3) atomic mass units. The mass number is the total number of nucleons (protons an neutrons) in the nucleus; the mass number is different for each isotope: 234U: mass number 234 235U: mass number 235 238U: mass number 238
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.
How much kg of uranium is required to become critical mass?
There is no single quantity, it depends on many factors some are:enrichment levelpresence/absence of moderatortype of moderatorpresence/absence of reflectorthickness of reflectortype of reflectorpresence/absence of absorbertype of absorberhas the uranium been compressed beyond standard densityetc.For some general order of magnitude values:in a typical water moderated reactor, the critical mass of the 3% enriched uranium is usually several tonsin a typical atomic bomb with a depleted uranium tamper/reflector, the critical mass of the 93.5% enriched uranium is 15 to 20 kg depending mostly on the thickness of the tamper/reflector

How much does uranium cost in square feet?
The square feet is a unit of area, not a unit for mass !!
How much uranium is left if a solid piece for one half life?
Half life is the time taken for half the atoms to decay. Whatever mass you start with, if it is a sample consisting of one pure uranium isotope, you will have half that mass of uranium after one half life. The piece of metal will not weigh half of the original mass, because the decay products will be there. In practice, a piece of uranium usually consists of a mixture of isotopes with different half lives.
How much does one square inch of uranium weigh?
The square inch is a unit of area. The cubic inch is a unit of volume; a cubic inch of uranium has a mass of approx. 312,2 grams.
How much does a box of uranium weigh?
Depending on the volume. Mass (g) = V (cm3) x 19,1
How much Uranium is in the sun?
It is estimated that about 1% of the mass of the sun is made up of heavy elements, which would include uranium. However, the exact amount of uranium present in the sun is difficult to determine due to the extreme conditions in its core.
How much does 1 cubic inch of uranium metal weigh?
Density of uranium: 19,1 g/cm3 1 cubic inch = 16,38706 cm3 The mass of 1 cubic inch of uranium is 313 g.
How much uranium is left if a solid piece exists for one half-life?
Half life is the time taken for half the atoms to decay. Whatever mass you start with, if it is a sample consisting of one pure uranium isotope, you will have half that mass of uranium after one half life. The piece of metal will not weigh half of the original mass, because the decay products will be there. In practice, a piece of uranium usually consists of a mixture of isotopes with different half lives.
How much uranium can be produced in comparison to other energy sources?
The production of uranium in each year is extremely small compared with the production of coal, oil, methane; but the most important is the energy obtained per unity of mass.
