β 11y agoIf half-life is 2.7 days then 8.1 days is three half-lives. 12.5%, or 12.5g, of AU-198 would remain.

β 13y agoAfter two half-lives - that is, twice the half-life - one quarter of the original amount will be left.

How do you determine the half life of a radioactive substance that has changed through radioactive decay After 40 days the original substance left is is one sixteenth of the original amount?
the halflife is 10 days
A sample of radioactive isotope has a halflife of 1 day how much of the original sample will be left at the end of the fourth day?
If a sample of radioactive material has a half-life of one week the original sample will have 50 percent of the original left at the end of the second week. The third week would be 25 percent of the sample. The fourth week would be 12.5 percent of the original sample.
The half life of Rn-222 is 4 daysWhat was the original mass of a sample of this isotope remains after 21 hrs?
The half-life on 222Rn86 is 3.8235 days. A sample of this isotope will decay to 0.8533 of its original mass after 21 hours. AT = A0 2(-T/H) AT = (1) 2(-21/(24*3.8235)) AT = 0.8533
A radioactive substance has has life of 5 days initial mass of 12kg how much the original isotope will remain after 10 days?
a radio active substance has half life of 5 days initial mass of 12kg.how much the original isotope will remain after 10 days?
The half life of iron 59 is 44.5 days how much of 2mg sample will remain after 133.5 days?
If the half-life of a nuclide is 44.5 days, then 178 days is four half-lives. After four half-lives, 0.0625 (0.54) of the original nuclide remains. If 50g is the original mass, then the mass after 4 half-lives is 3.125g. AT = A0 2(-T/H) A178 = (50) 2(-44.5/178) A178 = 3.125

How long does it take to get one pain pill out of your system?
The time between taking the pills and a clean system depends entirely on the drug in the pills, and specifically two properties: halflife and dosage. The more you take, the more work has to be done to get rid of it, and the longer it will take to get all the work done; the longer the halflife, the harder it is to get that work done and it will take longer as well.
