At an archaeological dig, the remains of a saber-tooth tiger are found. In a carbon dating ( 14C has a half-life of 5730 years) test to calculate the age of the cat, a scientist finds that the amount of 14C is about 1/32 the amount of 14C in living animals. How long ago did this saber-tooth tiger die?

In the carbon dating process for measuring the age of objects, carbon-14, a radioactive isotope, decays into carbon-12 with a half-life of 5730 years. A Cro-Magnon cave painting was found in a cave in Europe. If the level of carbon-14 radioactivity in charcoal in the cave is approximately 16% of the level of living wood, estimate how long ago the cave paintings were made. (Hint: Let the initial amount of carbon-14 be C0. Round your answer to the nearest year.)

11. My Notes Ask Your Teacher -/10 points Content Carbon dating An archaeologist finds some ancient jewelry made from bone. The jewelry has a carbon mass of 435 g (HINT: Assume all the carbon is 12C and determine the number of atoms) and careful measurements show that the remaining 14C has a current decay rate of 11 decays/s. Determine the age of the bone (and presumably the jewelry). Remember, the ratio of 14C to 12C when the animal died was...

Carbon 14 (14c) dating assumes that the carbon dioxide on Earth today has the same radioactive content as it did centuries ago. If this is true, the amount of 14c absorbed by a tree that grew several centuries ago should be the same as the amount of 14c absorbed by a tree growing today. A piece of ancient charcoal contains only 20% as much radioactive carbon as a piece of modern charcoal. How long ago was the tree burned to...

1. The remains of a pre-historic human are found. The mass of carbon in the sample is 8.5kg. The activity i.e. the number of decays per second is 700 decays/second. In living matter the ratio of 14c/?C=1.3. 10-12 14C is radioactive, whereas 12C is stable. Carbon's atomic mass is 12g per 6.02.102 atoms. The halflife of carbon is 5730 years.

The answer is not 13657.8
A piece of charcoal used for cooking is found at the remains of an ancient campsite. A 1.2 kg sample of carbon from the wood has an activity of 1660 decays per minute. Find the age of the charcoal. Living material has an activity of 15 decays/minute per gram of carbon present and the half-life of 14C is 5730 y.

If a radioactive isotope has half-life h, then the number of atoms in a sample is given by a(t)=a-2-/h where ao gives the number of atoms in the sample at time 0. The radio active decay of carbon-14 leads to clever way of determining the age of fossils and remnants of plants and animals. When an organism dies, the radioactive carbon- 14 in it decays, with half of it gone in 5,730 years. a. Suppose a mummified cat has a...
