What fraction of a sample remains after three half lives?
An eighth remains.
What fraction of a radioactive sample remains after three half - life?
It is 1/8 .
After three half-lives what fraction of a radioactive sample will remain?
Approx 1/8 will remain.
After three half-lives what fraction of a radioactive sample remains?
1/8 of the original amount remains.
Why After three half-lives what fraction of a radioactive sample remains?
After three half-lives, only 1/8 (or 12.5%) of the original radioactive sample remains. This is because each half-life reduces the amount of radioactive material by half, so after three half-lives, you would have (1/2) * (1/2) * (1/2) = 1/8 of the original sample remaining.
The fraction or ratio of a sample possessing a certain trait is called a?
The fraction or ratio of a sample possessing a certain trait is called a Proportion.
What fraction of a radioactive sample decays after three half lives?
If I take a radioactive sample of 400 moles of an unknown substance and let it decay to the point of three half-lives I would have 50 moles left of the sample. 1/2 of what is left will decay in the next half-life. At the end of that half-life I will have 25 moles left of the unknown substance or 4/25.
