A tree killed by being buried under volcanic ash was found to have a ratio of carbon-14 atoms to carbon-12 atoms of 5.2 × 10-14. The rate constant of the C-14 → C-12 decay is k = 1.21 × 10–4 yr–1 and the ratio of carbon-14 to carbon-12 is 1.2 × 10–12 in a contemporary sample. How long ago did the eruption occur in years?

(20 POINTS) 10.) An ancient wooden club is found that contains 6.5 kg of carbon. When recently measured, there were 8.0 x 1013 atoms of "C in the club. The decay constant for "C is 3.835 x 10-12 decays per second Assuming the ratio of C to 1"C atoms in living trees is 1.3 x 10-12, determine the age of the wooden club. Note that since the majority of the club's mass made up of 12C (then and...
