An archaeologist finds some ancient jewelry made from bone. The jewelry has a carbon mass of 468 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 12 decays/s. Determine the age of the bone (and presumably the jewelry). Remember, the ratio of 14C to 12C when the animal died was 1.3×10-12 & the half-life of 14C is 5730 y. age of bone =?

Please show me how to do this, thank you

Carbon Dating: All living organisms contain two isotopes (types) of carbon; carbon-12 ( 12C) and carbon-14 (14C). Carbon-12 is stable, meaning that its atoms do not decay. Carbon-14 however, is radioactive or unstable, meaning that an atom of carbon-14 may decay. It does this by throwing off an electron and thus transforming itself into Nitrogen 14. The ratio of carbon-14 to carbon-12 is the same for all living organisims, about 1/10, 000. However, once an organisim dies the carbon-14 begins...

Carbon-14 (14 6C) dating is a method for finding the age of an organic artifact from the quantity of 14 6C it contains. Carbon-14, an unstable isotope of carbon, follows a well-known sequence of decay processes. The decay constants of these processes have been well established, allowing researchers to determine the age of an artifact knowing both the original amount of 14 6C and the current amount. In the lab, it is relatively easy to measure the activity of a...
