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 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!
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
Analysis shows a carbon 14 ration of 0.712 between the cloth and present-day samples The half-life of carbon 14 is 5730 years How old is the cloth?
about 2800 years
What is the half-life of the radioactive isotope 6-C-14 element carbon?
The half-life of 6C14 is 5730 years, by Beta- decay.
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 is the half life of carbon -14?
The half-life of carbon 14 is 5,730 years.
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.
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.
Why cant carbon-14 be used to date material that is older than 75000 years?
Carbon has a half life of 5730 years. That means that after 5730 years there'll only be half the amount left. After about 11500 there will be a quarter of the original. After 75000 years there will be about 0.0001 of the original sample which is too small to date accurately?
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!
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
