the book density is:7g/cm3 or 0.007kg/cm3.
density equals mass over volume... 27 divided by 9 equals 3... so your answer is 3grams/centimetre cubed.
The density of this material is 1.5892 g/cm3 at 25 0C.
2.7g/cm3
0.869 g/mL
2.7 g
A critical mass is the smallest amount of fissile material needed for a sustained nuclear chain reaction. The critical mass of a fissionable material depends upon its nuclear properties (e.g. the nuclear fission cross-section), its density, its shape, its enrichment, its temperature and its surroundings.The minimum mass for a particular fissionable isotope will always be a sphere, as that is the shape which will lose the least neutrons for a given mass. The behavior of a sphere can be affected by its surroundings, if a neutron reflector is present this will reduce the amount needed. The easiest way to compare materials is to consider a bare sphere with no reflector. In this case Uranium 235 requires a mass of 52 kg and a sphere of diameter 17 cm. Plutonium 239 requires a mass of 10 kg and a sphere 9.9 cm diameter.The Wikipedia article 'Critical Mass' gives a table of other isotopes, but the above two are of most practical interest
The answer is 526.904 lbs (approx.). Kilogram is the SI unit of mass and pound is an imperial unit of mass. To convert from kg to pound, multiply the kg unit by 2.20462.
239 Fahrenheit is 115 Celsius.
The critical mass of the pure isotope plutonium-239 is 10 kg (a sphere with the diameter of 10 cm). The fission of one atom release hundreds of MeV.
Pu-239 has a half-life of 24,110 years.
PlutOnium 239 is an element - plutOnium - with an atomic weight of 239.
The population density of Liesveld is 239 people per square kilometer.
The population density of Idkerberget is 239 people per square kilometer.
Plutonium-239 and Uranium-235
Uranium is a radio active metal element. Atomic mass of it is 239.
There are 3 types of explosives used in nuclear weapons:conventional explosives, to rapidly assemble a subcritical mass into a supercritical mass of fissile material; many different explosives can and have been used.fissile material; highly enriched Uranium-235 and/or Plutonium-239.fusion fuel; Deuterium, Tritium, and/or Lithium Deuteride.
Protium, a rarely used name for hydrogen, has an atomic mass number of one, as well as an atomic number of one.
The population density of Horst aan de Maas is 239 people per square kilometer.
The mass number of the most important isotope of plutonium (239Pu) is 239. For the other isotopes see the link below; mass number = number of protons + number of neutrons).
Uranium-238 is a fertile nuclear material that is useful in producing fissile material (Plutonium 239)
No, the proton number decides, whether they are of the same element. In this case, they are isobars.
The relative atomic mass of the isotope 239U is 239,054 293 299 ± 0,000 002 052 (atomic mass units).
