How many half-lives have carbon gone through if 37245 years have passed and one half-life for carbon is 5730 years?
6.5 half-lives.
Carbon-14 has a half-life of 5730 years. how long does it take a 200-gram sample of carbon-14 decay to a mass of 100 grams?
5,730 years
How long does it take for radioactive carbon 14 to complete 4 half lives?
To complete 4 half lives, it would take 4 multiplied by the half-life of carbon-14. The half-life of carbon-14 is about 5,730 years, so it would take approximately 22,920 years for radioactive carbon-14 to complete 4 half lives.
The half-life of carbon-14 is 5730 years After 11460 years how much of the original carbon-14 remains?
Since the radioactive decay of 14C is first order, one can use the equation offraction remaining = 0.5^n where n is the number of half lives. 28650yr/5730 yr = 5 half lives. Thus..fraction remaining = 0.5^5 = 0.03125 or 3.125% would be remaining.
What is the age of a prehistoric mummified human skin that contains 12.5 percent of the original amount of carbon-14?
The half life of C-14 is about 5730 years and 12.5% is 100% x (.5)^3 so 3 half lives of the C-14 have occured. Now all you do is multiply 5730 years by 3 and get 17190 years. That's pretty old!
How many half-lives have carbon gone through if 37245 years have passed and one half-life for carbon is 5730 years?
6.5 half-lives.
What are 2 half lives of carbon 14?
The half-life of carbon-14 is approximately 5730 years. This means that after 5730 years, half of the original carbon-14 sample will have decayed. After another 5730 years (totaling 11,460 years), half of the remaining carbon-14 will decay.
What is the half life of carbon -14?
The half-life of carbon 14 is 5,730 years.
The half life of carbon 14 is 5730 years If a 1g sample of old carbon is one eighth as radioactive as 1g of a current sample then the age is about?
The ratio of radioactive carbon-14 in the old sample to the current sample is 1:8, suggesting 3 half-lives have passed. Since each half-life is 5730 years, the age of the old sample would be approximately 17190 years.
A carbon-14 sample starts with 100 atoms and 5730 years later there are 50 atoms. What is the half-life of carbon-14?
The half-life is 5730. This is because the half-life is the amount of time it takes for half of a sample to decay. In this case, the sample is 100 atoms, and half of 100 is 50, so the amount of time it takes the sample to reach 50 atoms is it's half life...5730!
Why can and rsquot carbon-14 be used to determine the age of fossils that are several hundred thousand years old?
The half life of C 14 is 5730 years. After a few half lives its useless.
The carbon 14 activity of a piece of ancient wood is one quarter of the new wood what is the age of the ancient wood if the half life of carbon-14 is 5730 years?
Given that the carbon-14 activity of the ancient wood is one quarter of the new wood, it means the ancient wood has undergone two half-lives (since 1/4 is 2^(-2)). Therefore, the age of the ancient wood would be 2 half-lives multiplied by the half-life of carbon-14 (5730 years), resulting in an age of 11,460 years.
The half-life of carbon-14 is 5730 years. How long will it take for the number of carbon-14 nuclei in a sample to drop to a quarter of the original number?
It will take two half-lives for the number of carbon-14 nuclei to drop to a quarter of the original number. Since the half-life of carbon-14 is 5730 years, it will take 2 * 5730 years = 11460 years for this to occur.
How many years after dying does a sample lose one-half of it carbon - 14 atoms?
5730 years (approx).
If the half-life of carbon-14 is about 5730 years then a fossil that has one-sixteenth the normal proportion of carbon-14 to carbon-12 should be about how many years old?
22900
Carbon 14 has a half life of 5730 In a plant fossil you find that this has decayed to a quarter of the original amount How long ago was this plant alive?
2 Half-Lifes= 1/4 Carbon 14 remaining. So 2 half lives have past. You add the 5730 years together to get 11460 years or 1.15*10^4 years.
When A carbon-14 sample starts with 100 atoms and 5730 years later there are 50 atoms. What is the half-life of carbon-14?
The half-life of carbon-14 is 5 730 years.
