How many half-lives have passed after 32 days?
If ' L ' is the number of days in one half-life, then the number of half-lives in 32 days is (32 / L) .
How long is 10000 days?
One hour 15 minutes and 46 seconds if you're referring to the album. If you are referring to real life then its 27 years 4 months and 15 days.
The half of iodine-125 is 60 days.What fraction of iodine-125 nuclides would be left after 360 days?
Assuming that "half" refers to "half-life", 360/60 = 6 so fraction left = 1/26 = 1/64
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.
What fraction of U-238 atoms present at 1 half-life remain after 2 half-lives?
1/2 (50%) of them.
What is the shelf life of half and half?
4 days
What is the lifespan of the Mu meson?

How much of a 100.0 g of gold- 198 after 8.10 days if its half-life is 2.70 days?
If half-life is 2.7 days then 8.1 days is three half-lives. 12.5%, or 12.5g, of AU-198 would remain.
A particle element has a half-life of 27 days after 54 days have elapsed how much of the radioactive material is left is called?
54 days is 2x27. After one cycle of a half life (27 days), one-half of the substance would be left. After a second cycle of a half life (27 more days, for a total of 54), one-half of one-half is left, or one-fourth.
What is the half-life of an isotope decreased to one-half its original amount in six days?
six days
If Half life of radioactive material is 50 days. how many half life it will take to become 12.5 percent of the original amount?
after two half life periods ( 100 days) it becomes 12.5 %.
What is meant by the statement that the half life of thorium is 24 days?
Half life is the period of time after that the amount of a material is reduced by half.The isotope thorium-234 has a half life of 24,10(3) days.
What is the Half life of penicillin?
Generally 1 hour or less.
If a 100 g sample of radioactive element decays to 25 g in 4 days what is the half-life of the element?
The half-life of this element will be 2 days since it will lose half its mass in the first two days, so 100g to 50g, then half the resulting mass in the next two days (now totaling 4 days), so 50g to 25g in four days. So the half-life (in case the above was a bit rambling) is 2 days - at which point the element has lost half its original mass...which, of course, is what a half-life is :))
What is the half-life of radon?
The half life of 222Rn, the naturally found isotope of radon, is 3.8235 days.
What is the half-life of phosphorus-32?
The half-life time of P-32 is 14.3 days.
How much of a 100.0 g sample of 198Au us left after 8.10 days if its half-life is 2.70 days?
8.1 days is, if half-life is 2.7 days, 3 half-lives. 12.5%, or 12.5 g, of 79198Au would remain after three half-lives.
