If carbon-14 has a decay half-life of 5730 years, what fraction of the original carbon-14 would you expect to remain intact in a 3000 year old parchment scroll, and why?
The half-life of carbon-14 is 5730 years. How long does it take for 3.6 grams of carbon-14 to be reduced to 1.3 grams of carbon-14 by radioactive decay? years (Do not round until the final answer. Then round to the nearest hundredth as needed.)
This Question: 1 pt 20 of 20 (15 complete The half-life of carbon-14 is 5730 years. How long does it take for 2.2 grams of carbon-14 to be reduced to 0.2 grams of carbon-14 by radioactive decay?

Dinosaur fossils are too old to be reliably dated using carbon-14, which has a half-life of about 5730 years. Suppose we had a 66 million year old dinosaur fossit. How much of the living dinosaur's 14c would be remaining today? (Round your agswer to flve decimal places.) % Suppose the minimum detectable amount is O.7 %. What is the maximum age of a fossil that we could date using 14c7 (Round your answer to the nearest integer) Need Help? Read...
1. The half-life of carbon-14 is 5730 years. A sample is found to have one-eighth the original amount of carbon-14 in it. How old is the sample? 5730 years, 716 years, 45800 years, 17200 years 2. Why wouldn't you use carbon-14 dating on a piece of shell that was estimated to be 1 million years old? Sea shells do not have radioisotopes, carbon dating is only useful on plants, uranium dating is better for items older than 1/2 million years,...
Part D A fossil was analyzed and determined to have a carbon-14 level that is 30 % that of living organisms. The half-life of C-14 is 5730 years. How old is the fossil? Express your answer with the appropriate units. View Available Hint(s) μΑ ? t = Value Units
The amount of carbon-14 present in animal bones after t years is given by P(t) = Poe -0.00012! A bone has lost 36% of its carbon-14. How old is the bone? The bone is years old. (Round to the nearest integer as needed.)

Some fossil bones containing 1/32 of their original amount of carbon-14 are found. How many half-lives have passed? How old are the bones? (HINT: The half-life of carbon-14 is 5,730 years. If 1/8 of the original amount of carbon-14 was present, 1/8 = 1/23 or 1/(2x2x2), therefore 3 half-lives would have passed and therefore, the bones would be 5,730 years x 3 = 17,190 years old)
