After 6 half-lives What percentage of a radioactive sample remain?
After 6 half lives, the remaining will be (1/2)6 i.e 1/64 th of the initial amount. Hence by percentage it would be 1.5625 %
How much sample of 10g of tritium with half life of 12.32 after 2 half lives?
After 2 half-lives (two half-lives of tritium is 12.32 x 2 = 24.64 years), the initial 10g sample of tritium would have decayed by half to 5g.
How much thorium-234 will remain after 2 half lives?
After 2 half-lives, 25% of the original amount of thorium-234 will remain. This is because half of the substance decays in each half-life period.
How much iodine has decay if 5 half lives have passed?
After 5 half-lives, 31.25% of the original iodine remains, meaning 68.75% has decayed. Each half-life reduces the amount of the original substance by half, so after 5 half-lives, the remaining fraction is ( \left(\frac{1}{2}\right)^5 = \frac{1}{32} ). Therefore, the decay percentage is calculated as ( 1 - \frac{1}{32} = \frac{31}{32} ), which is approximately 96.875%.
The amount of material left after two half-lives is one-half of the original amount?
After two half-lives, only one-fourth (1/2 * 1/2 = 1/4) of the original material remains. Each half-life reduces the amount by half, so after two half-lives, the remaining material is one-fourth of the original amount.
After 6 half-lives What percentage of a radioactive sample remain?
After 6 half lives, the remaining will be (1/2)6 i.e 1/64 th of the initial amount. Hence by percentage it would be 1.5625 %
What percentage of a radioactive sample remains after 5 half-lives?
After 5 half-lives, 3.125% (or 1/2^5) of a radioactive sample remains. Each half-life reduces the sample by half, so after 5 half-lives, there is only a small fraction of the original sample remaining.
What percentage of a radioactive element will be left after 1 half-life?
Half life is pretty much self explanatory in that after they go through 1 half life half of the radioactive decay remains. 1/2 x 1/2 x 1/2 = 1/8 = 0.125 = 12.5% or you can divide 100% by 2, 3 times and you'll get 12.5%
How do you say 1 half in percentage?
1 half in percentage = 1/2% (one-half percent)
What is the percentage of radioactive nuclei left after 3 half-lives have passed?
12.5%
What is the equivalent percentage of half of 1?
equivalent percentage of half of 1 = 50% half of 1 = 1/2 * 1 = 1/2 1/2 * 100% = 50%
How much sample of 10g of tritium with half life of 12.32 after 2 half lives?
After 2 half-lives (two half-lives of tritium is 12.32 x 2 = 24.64 years), the initial 10g sample of tritium would have decayed by half to 5g.
What percentage is one half?
As a percentage 1/2 = 50%
What percentage of a radioactive element will remain after seven half lives?
After seven half lives, approximately 0.78125% (1/2^7) of the original radioactive element will remain. This can be calculated by repeatedly halving the remaining amount after each half life.
What is 2 and a half as a percentage?
250%
What percentage is half of a half?
Half of a half is equivalent to 1/2 * 1/2, which equals 1/4. To convert this fraction to a percentage, you multiply by 100. Therefore, half of a half is 25%.
How long does it take for this radioactive material to decay through 2 half-lives?
It will take twice the half-life of the radioactive material for it to decay through two half-lives. If the half-life is 1 hour, it will take 2 hours for the material to decay through 2 half-lives.
