If you have 100 grams of plutonium-239 how many grams of plutonium-239 will remain after 24000 years?

Slightly over 50 grams; the half-life of Pu-239 is around 24110 years, so in 24000 years a little less than half will have decayed to U-235.

How many years is 24000 days?
24,000 days = 65.71 years.
A Radio Decay Isotopes Has A Half Life Of 100 Years . A Sample Of 40 Grams Of The Isotopes Will Have A Mass Of Grams In 200 Years?
After 100 years, half of the original sample (20 grams) will remain. After another 100 years (total 200 years), only half of that amount (10 grams) will remain.
If the initial quantity is 5 grams how much remains after 600 years?
That depends what assumptions you make about what the 5 grams of matter is made of.
If Ra-226 had a f life of 1600 years and you have 20 grams how much will be left in 3200 years?
After 1600 years, half of the 20 grams of Ra-226 will remain, so 10 grams will be left. After another 1600 years (3200 years total), half of the remaining 10 grams will remain, resulting in 5 grams of Ra-226 left.
how many months are in 200,000 years?
24000 a month
How much of an 800-gram sample of potassium-40 will remain after 3.9109 years of radioactive decay?
100 grams
If a smoke detector initially contains 1 gram of Americium 241 how much will remain in 432 years?
0,5 grams
How many grams remain after 20 years?
It depends on the substance and its rate of decay. The amount remaining can be calculated using the substance's half-life and the initial amount present.
How much of an 800-gram sample of potassium-40 will remain after 3.9 X 109 years of radioactive decay?
100 grams
How Many Halflife Are These In A 100-year Span How Many Grams Of The Sample Would Remain At The End Of The 100 Years?
If the substance has a half-life of 10 years, there would be 10 half-lives in a 100-year span. Each half-life reduces the amount by half, so after 100 years, 1/2^10 = 1/1024 grams of the sample would remain.
How many years to use up 400000.00 earning 4 percent interest taking 24000 a year?
Assuming interest compounded annually, at the end of 29 years there will be only 270 in the account so it will not be possible to take 24000 in the 29th year.
If the interest is 24000 if the principle is 4000 and the term is 2 years what is the rate?
The interest is 300% per year.
