After three half-lives what fraction of a radioactive sample remains?
1/8 of the original amount remains.
After three half-lives what fraction of a radioactive sample will remain?
Approx 1/8 will remain.
What is the equivalent fraction three fifths?
equivalent fraction of three fifths = 6/10
What is a fifth of a fraction plus three fifths of fraction?
4/10
What is three tenths as a decimal fraction?
Three tenths is .3 as a decimal.
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.
What fraction of a sample remains after three half lives?
An eighth remains.
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.
After three half-lives what fraction of a radioactive sample will remain?
Approx 1/8 will remain.
What fraction of a radioactive sample remains after three half-lives?
Not sure what you mean by "had-lives". After 3 half lives, approx 1/8 would remain.
Sample of the three models of a fraction?
There are three models of a fraction namely area model, liner model and set model.
What fraction of a radioactive sample remains after three half lives?
Not sure what you mean by "had-lives". After 3 half lives, approx 1/8 would remain.
Is a radioactive sample has decayed until only one eighth of the original sample remains unchanged how many half lives have elapsed?
Three half lives have elapsed. This can be determined by calculating how many times the original sample size must be halved to get to one eighth: (1/2) * (1/2) * (1/2) = 1/8.
How does half life work in the context of radioactive decay?
In the context of radioactive decay, half-life is the time it takes for half of the radioactive atoms in a sample to decay. This means that after one half-life, half of the original radioactive atoms have decayed, and after two half-lives, three-quarters have decayed, and so on. The concept of half-life helps scientists understand the rate of decay of radioactive substances.
Which of the following is not a component of the radiation emitted by a radioactive sample a.alpha radiation b.delta radiation c.gamma radiation d.beta radiation?
Radioactive substances can emit alpha particles, gamma radiation (gamma rays) and beta radiation (beta particles). What they do not emit is delta radiation.It causes transmutation.It has a mass of 4 amus.
What is the amount of time it takes for three fourthsof a radioactive sample of an isotope of bromine to decay if the half life of the isotope is 16.5 hours?
It takes one half-life for half of the radioactive sample to decay. Since half of the sample has decayed after 16.5 hours, it will take another 16.5 hours for the remaining half to decay, totaling 33 hours to decay three fourths of the original sample.
