How long will it take 24 grams of plutonium -240 to Decay to 20 gram?
The half-life of plutonium-240 is about 6,560 years. If 24 grams decay to 20 grams, it represents a loss of 4 grams of plutonium. The time it would take for 24 grams to decay to 20 grams would depend on the specific decay rate and is typically calculated using exponential decay equations.
How long will it take 36 grams of plutonium-240 to decay to 12 grams in years?
The half-life of plutonium-240 is about 6,560 years. To find the time it takes for 36 grams to decay to 12 grams, we can use the formula N = N0 * (1/2)^(t/t1/2), where N is the final amount, N0 is the initial amount, t is the time, and t1/2 is the half-life. Substituting the values, we find that it will take approximately 13,120 years for 36 grams of plutonium-240 to decay to 12 grams.
Plutonium-240 decays according to the function Q(t)=Q 0 e^ -kt where Q represents the quantity remaining after t years and k is the decay constant 0.00011 ... To the nearest 10 years , how long will it take 36 grams of plutonium-240 to decay to 12 grams?
To find the time it takes for 36 grams of plutonium-240 to decay to 12 grams, we can set up the equation 12 = 36 * e^(-0.00011t) and solve for t. The result is t ≈ 180 years. Therefore, it will take approximately 180 years for 36 grams of plutonium-240 to decay to 12 grams.
How long does it take plutonium to decompose?
depends on the type of waste, that determines its halflife. some waste will be safe in just a few decades, other types will take millions of years. if they would reprocess reactor nuclear waste so that uranium, plutonium, and other transuranics were recycled as fuel instead of staying in the waste; the remaining waste could be stored in a repository for 100 to 200 years and be safe after that.
Uranium-235 has a half-life of 700 million year. how long does it take a 100 gram sample of uranium to decay to a mass of 50 grams?
If a radioactive isotope has a half-life of 4 years, than 0.125 (0.53) of the isotope will remain after 12 years, or 3 half-lives.The question asked about Uranium. There is no isotope of Uranium with a half-life of 4 years. The closest is 232U92, which has a half-life of 68.9 years.Reference: http://www.nndc.bnl.gov/chart/

Each isotope has another half life.
How long will it take 36 grams of plutonium-240 to decay to 12 grams in years?
The half-life of plutonium-240 is about 6,560 years. To find the time it takes for 36 grams to decay to 12 grams, we can use the formula N = N0 * (1/2)^(t/t1/2), where N is the final amount, N0 is the initial amount, t is the time, and t1/2 is the half-life.

How long will it take 27 grams of plutonium-240 to decay to 9 grams?
The decay of plutonium-240 follows exponential decay kinetics, where the amount remaining is given by the equation: N(t) = N0 * e^(-λt), where N(t) is the amount remaining at time t, N0 is the initial amount, λ is the decay constant, and e is the base of the natural logarithm. The decay constant for plutonium-240 is 0.0106 years^-1. By rearranging the equation to solve for time (t) when N(t) = 9 grams and N0 = 27 grams, you can calculate the time it will take for 27 grams of plutonium-240 to decay to 9 grams. The calculated time will be approximately 20.5 years.

How long does it take for 1kg of plutonium to decay to 1g?
The half life is different for each isotope of plutonium; name the isotope for a calculation.
How long does it take for 200 grams of carbon 14 to decay into 100 grams?
The half-life of carbon-14 is about 5700 years. This means that in 5700 years, half of the original 200 grams (100 grams) will have decayed. To decay from 200 grams to 100 grams, it will take one half-life, or 5700 years.
What is the nuclear decay equation for plutonium 239?
The first step is an alpha decay to (guess what!) uranium 235. You can probably take it from there.
After 7 minutes a 53 g sample of plutonium decays to 36 g how long will it take for the sample to decay to 13 of its original amount?
It will take 25.0898 minutes, approx.
How long does it take a 5-gram sample of uranium- 235 to decay to a mass of 2.5 grams?
One Half-Life :-)
How long would it take for plutonium to decay to one eighth of its original activity?
For plutonium (or any other radionuclide) to decay to one eighth of its original activity, it will take 3 half-lives of the material. In one half-life, half is gone. Half will be left. In another half-life, half of the half that was left is gone, and one quarter will be left. In a third half-life, half the one quarter will be left, and that's one eighth of the original. In the case of plutonium, there are a number of isotopes of this highly radioactive stuff. The isotope 239Pu, which is commonly used in nuclear weapons, has a half-life of 2.41 x 104 years. That's 24,100 years. For 239Pu to decay to 1/8 th of its original amount, it will take 3 time the half-life, which is 7.23 x 104 years, or 72,300 years. And yes, that is a long time. A very long time....
