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 grams remain after 20 years?
100 grams
How many years is 24000 days?
24,000 days = 65.71 years.
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.
How much of an 800-gram sample of potassium-40 will remain after 3.9109 years of radioactive decay?
100 grams
how many months are in 200,000 years?
24000 a month
The half-life of actinium 227 is 21.772 years After 50 years how much of a 1500 g sample will remain radioactive?
Approx. 313 grams
If a smoke detector initially contains 1 gram of Americium 241 how much will remain in 432 years?
0,5 grams
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 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.
If a sample contains 100g of a radioactive isotope how much will be left after 3 half lives?
There will be 125 grams of radium left. Keep it simple. Ih a half-life, half the sample decays. Half of 1000 grams is 500 grams, then half of 500 grams is 250 grams. Half of that again is 125 grams. And just so you know, the half-life of radium-226, the non-synthetic isotope of radium, is 1602 years. If this was the case here, 4806 years would have to pass to get the sample to decay as far as it did.The remained quantity of radium after 3 x 1602 years is 125 grams.
How many grams of radium-226 will remain from 5 grams after 365 years if the half life of radium 226 is 1600?
The question, as posed cannot be answered because you have not stated the units for the half-life. Some things have half lives of millions of years while others have half-lives measured in micro-seconds. Fortunately, Wikipedia came to my rescue and the half-life is 1600 years (approx). The answer is approx 4.3 grams.
