232Th decаys by а series оf аlpha and beta decays tо give stable 208Pb. 232Th has a very lоng half life t1/2 = 14 billion years. Other than the stable Pb, the other products in the decay series are relatively short-lived. Suppose that a sample of rock contains 232Th and 208Pb, where all of the Pb is due to decay of the Th. If Th and Pb are present in a molar ratio Th/Pb = [ratio], what is the age of the rock? Give your answer in billions of years. (1 billion = 109) ln(2) = 0.6931
