Be sure to answer all parts. The carbon-14 decay rate of a sample obtained from a young tree is 0.264 disintegration per second per gram of the sample. Another wood sample prepared from an object recovered at an archaeological excavation gives a decay rate of 0.193 disintegration per second per gram of the sample. What is the age of the object? (The half-life of carbon-14 is 5715 years.) × 1 ol 1 years Enter your answer in scientific notation.

An archeological artifact was subjected to radiocarbon dating. The artifact showed a carbon-14 decay rate of 12.2disintegrations/min per gram of carbon. Carbon-14 has a half-life of 5715 years, and currently living organisms decay at the rate of 15.3 disintegrations/min per gram of carbon. What is the approximate age of the artifact? Select one: A. 371 years old B. 6597 years old C. 851 years old D. 1867 years old

(4) (1 pt) A sample of bone is subjected to radiocarbon dating. The current decay rate observed for its carbon-14 content is 11.2 disintegrations per minute per gram of carbon. What is the age (in years) of the bone? The half- life for carbon-14 is 5.73x10 yrs., and the decay rate for carbon-14 in living organisms is 15.3 disintegrations per minute per gram of carbon.

Radiocarbon dating of a sample of wood from the tomb of an Egyptian pharaoh found that in the 1 gram of the sample there were 9.843 times 10^-15 mol of C-14 and 1.202 times 10^-2 mol of C-12. The C-14 isotope is radioactive and decays with a half-life of 5, 730 years: the C-12 isotope is stable (does not decay). If the initial ratio of these isotopes is known to have been Number of C-14/Number of C-12 = 1.20 times...

A 50.0 g sample of carbon is taken from the pelvis bone of a skeleton and is found to have a C-14 decay rate of 200.0 decays min‐1. It is known that carbon from a living organism has a decay rate of 15.0 decays min‐1g‐1 and a half-life of 5,730 years. Find the age of the skeleton in years. (please show ALL work and type your answer or write neatly please!)
