Question 7 1 pts The AC activity of an artifact from a burial site was 8.7/min.g C. The half-life of C is 5730 years, and the current activity is 16.1/min.g C (that is, 16.1 disintegrations per minute per gram of carbon). How old in years) is the artifact? Enter number to 1 decimal place. Question 8 1 pts Analysis of an ant found in a piece of amber provided 10 disintegrations of 14C/min.g C, whereas...

(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...
