Carbon 14 dating The technique of carbon 14 (4C) dating is used to determine the age of archaeological and geologi- cal specimens. The formula T = -8310 In x is sometimes used to predict the age T (in years) of a bone fossil, where x is the percentage (expressed as a decimal) of 14C still pres- ent in the fossil. (a) Estimate the age of a bone fossil that contains 4% of the 14C found in an equal amount of carbon in present- day bone. (b) Approximate the percentage of "C present in a fossil that is 10,000 years old.
