How many kilograms of Uranium-238 did the bombs dropped on Hiroshima and Nagasaki each contain?

None. The first atomic bomb was made with enriched uranium. Note: There is a "slight technicality" with this one. Here's the deal. Any time that a small quantity (or a slightly larger quantity) of uranium is found, either in nature or in the physics lab, there will be a tiny bit of plutonium in the sample. Only the tiniest bit, but it will be there. Uranium's isotopes are all unstable, and they will decay by spontaneous fission or alpha emission. Within that decay environment, a few atoms of uranium are transformed into atoms of plutonium. As stated, it's a "technicality" as such, but it's a fact.

∙ 11y agoThe fissile isotopes used in the first bombs are the same as used in current bombs: Uranium-235 and/or Plutonium-239. Plutonium is most common, as can be seen from the following list of the first 5 bomb detonations:
- Trinity proof test, Plutonium-239
- Little Boy, Uranium-235, first combat use, Hiroshima
- Fat Man, Plutonium-239, second & last combat use, Nagasaki
- Crossroads Able effects test, Plutonium-239
- Crossroads Baker effects test, Plutonium-239

∙ 9y agoThe Hiroshima bomb (little boy) contained only highly enriched uranium (approx. 64 kg).
The Nagasaki bomb (Fat man) contained depleted uranium only as a damper. The explosive was plutonium.

∙ 11y agoThe two dropped in WW2 weighed 4.5 tons and 5 tons.
Since then bombs have been built as light as about 50 pounds to as much as about 500 tons.

What mass of iron ore in kilograms will contain 15.64 grams of iron if the ore contains 0.257 iron by mass?
The mass of iron ore is 6,085 kg.
How many kilograms are in one cubic meter?
The medium density should given to convert from mass (kilogram) to volume (1 cubic meters). Assuming water of 1000 kg/cubic meter, than 1 cubic meter would contain 1000 kilograms,
Where can one find a kilos to pounds conversion chart?
Kilograms to pounds conversion tables can be found at a number of online sites. The web domains "Metric-Conversions" and "ManuelsWeb," for example, both contain these charts.
Water its 11.2 percent by mass hydrogen How many kilograms of water would contain 5.0 grams of hydrogen?
let 'x'g of water contain 5.0g of hydrogen. 11.2%=11.2/100g=0.112g x*0.112=5.0g of hydrogen. x=5.0/0.112 x=44.642857g. water is 45g.
What element did the atomic bomb Fat man use Plutonium or Uranium Dan Brown's book says Uranium-238 but others say it's Plutonium?
The Nagasaki bomb 'Fat Man' was plutonium, as was the first nuclear device ever exploded, called the 'gadget', in the Trinity test near Alamogordo, New Mexico.In between these, the first bomb ever used in war was dropped on Hiroshima. This was the gun-type uranium bomb.Uranium-238 cannot support the fast neutron chain reaction required to get an explosion.Note: both bombs DID contain significant amounts of Uranium-238, but it was used as a high density 'tamper' material to contain the blast a few extra microseconds to maximize yield, not as the fuel. It just vaporized and mixed into the fallout as uranium oxides.
How many kilograms of Plutonium did the bombs dropped on Hiroshima and Nagasaki each contain?
The "Fat Man" implosion bomb detonated over Nagasaki (the second bomb dropped on Japan by the US) contained 6.2 kilograms of Plutonium alloy (Pu-239, Pu-240 and Gallium). The "Little Boy", first bomb dropped on Japan by the USA was not a Plutonium implosion bomb. It was a gun-type bomb and contained 64 kilograms of Uranium-235.
Why were atomic bombs dropped only in nagasaki and why hiroshima out of the whole of japan?
doesn't really answer your questionduring the closing stages of the war against japan, japan was extensively fire bombed by the Americans. all the major industrial cities were basically destroyed. hiroshima kokura and nagasaki all had something in commonthey were coastalthey were surrounded by mountainsthey had minor military factories and portsthey had approximately 250,000 in populationthese cities were left basically untouched by the Americans during all of the bombings of japan. why?being surrounded by mountains it would contain the blasthaving ports and military targets gave a good reason for bombingsif you bombed Tokyo or Osaka you would kill a million plus civilians (not acceptable in public opinion) but believe it or not 250,000 is acceptable.they were dropped on those cities because they were perfect test sites for the atom bomb. you may ask what has kokura to do with it. kokura was the secondary target for the hiroshima bombing and the primary target for the nagasaki bombing. the bombs need to be dropped in fine weather for bombardier accuracy and to take arial phots of the effects. luckily for the people of kokura on the day of the hiroshima bombing it was fine in hiroshima and on the day of the nagasaki bombing it was overcast in kokura so they missed out.i hope this answered your question.Those two bombs were enough to kill thousands and thousands of people and to bring Lapan to it knees.
Which bomb caused the most destruction Little Boy or Fat Man?
The Liitle Boy caused more damage because the city of Hiroshima was in a flatter landscape. The Fat Man of Nagasaki was less devastating because that city is in a "bowl". The mountains surrounding that city helped to contain some of the force of the bomb. It could not spread out as much as the Little Boy did.
What destruction happened during the Hiroshima bombs?
NO DOUBT WITH NUCLEAR BOMB ATTACKS ON JAPAN THERE WAS DESTRUCTION OF LIFE AND PROPERTY BUT ALONG WITH THAT THERE WAS A SEREIOUS IMPACT OF BOMBING ON PEOPLE , THAT IS DEFORMITIES FOUND IN PEOPLE , BECAUSE BOMBS CONTAIN RADIOACTIVE MATERIAL WHICH EMITS HARMFUL RADIATIONS. THESE HARMFUL RADIATIONS HAS THERE EFFECT GENERATION AFTER GENERATION AS THESE RADIATIONS CAUSE GENETIC DISEASES. THESE DEFORMITIES DUE TO BOMB STILL CAN BE SEEN IN HIROSHIMA AND NAGASAKI. IT WAS MOST HARMFUL DESTRUCTION.
How many moles are in 1.0 kilograms of NaCl?
1 kg NaCl contain 17,112 moles.
How much kgs 1 micro ton contain?
A ton has 1000 kilograms. Therefore, a micro-ton (millionth of a ton) has 1000 kilograms / 1,000,000, or 0.001 kilograms. Note: This is not a commonly used name; a microton would just be called a gram.
What statement would be included in biographical summary of harry struman?
Harry S. Truman was the 33rd President of the United States, serving from 1945 to 1953. He became president upon the death of Franklin D. Roosevelt and is known for making the decision to drop atomic bombs on Hiroshima and Nagasaki, leading to the end of World War II. Truman also implemented the Truman Doctrine and Marshall Plan to contain communism in Europe.
Why did Nagasaki and Hiroshima pay the price?
In 1941 in the month of December, Japan attacked Pearl Harbor without notice dragging the United States into World War 2. Four years after that, after a ferocious war, the United States dropped an atomic bomb on Nagasaki and Hiroshima on August 6 and 9, 1945 ending the war.The cities of Hiroshima and Nagasaki were selected as targets after exhaustive study by military specialists. Criteria for the selection of the targets included the following:The range of the aircraft which would carry the bomb.The desirability of visual bombing in order to insure the most effective use of the bomb.Probable weather conditions in the target areas.Importance of having one primary and two secondary targets for each mission, so that if weather conditions prohibited bombing the target there would be at least two alternates.Selection of targets to produce the greatest military effect on the Japanese people and thereby most effectively shorten the war.The morale effect upon the enemy.Since the atomic bomb was expected to produce its greatest amount of damage by primary blast effect, and next greatest by fires, the targets should contain a large percentage of closely-built frame buildings and other construction that would be most susceptible to damage by blast and fire.The maximum blast effect of the bomb was calculated to extend over an area of approximately 1 mile in radius; therefore the selected targets should contain a densely built-up area of at least this size.The selected targets should have a high military strategic value.The first target should be relatively untouched by previous bombing, in order that the effect of a single atomic bomb could be determined.Hiroshima and Nagasaki had been virtually untouched by previous bombing and fit other criteria. Hiroshima contained the headquarters of the 2nd Army. It had concrete buildings in the center of the city, but many wooden workshops and houses outside the center of the city.Kokura was the primary target for the second bombing but was covered in smoke so the bomber crew changed their target to the secondary target, Nagasaki. Nagasaki was an important sea port with many and varied industries, many of which were related to the production of war materials. Most of the residences in Nagasaki were contructed of wood and many of the smaller industries and business establishments were also housed in wooden buildings or flimsily built masonry buildings.

Did the atomic bomb junior contain a paper saying KABOOM?
Well, first of all, the bomb was called "Little Boy" and was dropped on Hiroshima. The paper saying "Kaboom!" is considered to be an urban legend - a "tall tale".
