The standard hydrogen bomb is a Teller-Ulam design which utilizes a Fission-Fusion-Fission sequence.
The primary is a fission device, likely boosted with tritium, not too different from the Fat Man implosion bomb used over Nagasaki; although it is much more efficient. The minimum critical mass for Pu-239 is about 25 pounds (11kg).
The secondary is a fusion-fission device, utilizing the x-ray radiation from the primary to compress & heat a light element. At the center of this is a hollow tube of Pu-239. As the secondary compresses, the Pu-239 tube (aka "spark plug") compresses as well and achieves criticality giving a fission reaction. This may require another 25 pounds (~11kg) of Pu-239.
So a rough estimate is about 50lbs (~22kg) for both fission processes. However, there are ways to create a super-critical mass using less material through the use of neutron reflectors, tritium boosting, neutron-initiators and other methods that are not common knowledge.
Nations that possess nuclear weapons don't give precise details for reasons of national security, so an exact answer to your question would require a security clearance of some sort, and a need to know.
So the best answer to your question is not much more than 50 pounds, or 11kg per weapon, probably a lot less.

How much plutonium would be needed to build a standard hydrogen bomb?
The first plutonium fission bomb used 6.2 kilograms of plutonium.The first stage of a hydrogen bomb is a fission bomb. By using better explosives to compress the plutonium and tritium gas boosting it is probably possible to use 2 kilograms to 3 kilograms of plutonium here.Each fusion stage uses a plutonium "sparkplug" rod that runs the length of that stage to initiate fusion. The exact dimensions (and thus the weight) of plutonium used here is classified Top Secret Restricted Data. It is possible that these "sparkplugs" may even be hollow tubes (to allow neutrons a free path the entire length), which might eliminate more than 90% of the weight of a solid rod while improving its performance.As a "ballpark guess" without reliable data to base it on, each stage of a modern hydrogen bomb (both the fission first stage and all fusion stages) probably uses less than 3 kilograms of plutonium.A standard two stage hydrogen bomb would then use less than 6 kilograms of plutonium and a three stage hydrogen bomb (the largest size ever built) would then use less than 9 kilograms of plutonium.
How much plutonium is in the second atomic bomb?
Nagasaki (Japan) - 9 August 1945 - a bomb containing 6,4 kg of Plutonium 239
How much did the plutonium device cost for the nuclear bomb?
The cost of the plutonium used in a nuclear bomb can vary greatly, depending on factors such as purity, quantity, and production method. However, estimates suggest that the plutonium used in a typical nuclear bomb could cost millions of dollars.
How much TNT is in a Plutonium Bomb?
Nuclear weapons with plutonium don't contain TNT.
Which is more destructive a nuclear bomb or a hydrogen bomb?
A hydrogen bomb (thermonuclear bomb) is more destructive than a regular nuclear bomb (fission bomb). Hydrogen bombs release much larger amounts of energy and have the potential to create significantly more devastation and damage.
How much plutonium used in nuclear bomb?
In the Nagasaki bomb, about 14 pounds. Design criteria on later weapons is classified.

How much plutonium was USED in little boy?
The Little Boy atomic bomb used about 64 kilograms (141 pounds) of highly-enriched uranium-235, not plutonium. Plutonium was used in the Fat Man bomb, which used about 6.2 kilograms (13.6 pounds) of plutonium.

How is fussion bomb different from a fission bomb?
Fusion reaction combines isotopes of hydrogen to make helium and release energy. This requires temperatures in the millions of Kelvins to start.Fission reaction breaks up isotopes of heavy elements (Uranium & Plutonium) into lighter elements (fission fragments, a major part of fallout) and release energy. This can start a normal temperatures.
How much plutonium is in an average atomic bomb?
ugh there was 10000kgs in fatman aka 100 sticks
What kills more h-bomb or a-bomb?
different letters in the alphabetAn "A-bomb" is usually a fission bomb (plutonium or Uranium fissions = splits into lighter elements)An "H-bomb" is a fusion bomb wherein Hydrogen (or some isotope of it) "fuses" into heavier elements. Often an H-bomb needs the energy of an A-bomb to start its nuclear reaction but the output is SO much greater that the A-bombs energy output is dwarfed by the enormous fusion explosion.
How much hydrogen is in a hydrogen bomb?
there is no Hydrogen in a hydrogen bomb.its called a hydrogen bomb because there are isotopes of hydrogen: tritium (3H ), and deuterium (2H,)
Why is plutonium heavier than hydrogen?
Plutonium has a significantly higher atomic number and more protons and neutrons in its nucleus compared to hydrogen, making it much heavier. The mass of an atom is determined by the number of protons and neutrons it has, so the additional particles in a plutonium atom contribute to its greater weight.
