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?
9,990 years
How many centimeters are in a gram?
Centimeters measure length, for example, a ruler is 30 centimeters long, and grams measure mass (how heavy something is), for example a recipe may need 50 grams of sugar. It is not possible to put centimeters in terms of grams, since they measure very different things.
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/
How long will it take for a 64 gram sample to decay to 8 grams if the half life of the isotope is 5 hours?
50 grams to 12.5 grams is a reduction of 0.75, or an ending amount of 0.25. That is two half-lives, or twenty years, in this case. The equation of half-life is ... AT = A0 2(-T/H) ... where A0 is the starting activity, AT is the ending activity at time T, and H is the half-life at units of T.

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.
