The carbon−14 decay rate of a sample obtained from a young tree is 0.350 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 0.182 disintegration per second per gram of the sample. What is the age of the object? Hint: The rate constant for carbon−14 decomposition is 1.21 × 10−4 yr−1. Report your answer to 3 significant figures.
