Q1. after three half-lives of an isotope, 1 billion of the original isotope's atoms still remain in a certain amount of this element. how many atoms of the daughter product would you expect to be present?
q2. by measuring the amounts of parent isotope and daughter product in the minerals contained in a rock, and by knowing the half-life of the parent isotope, a geologist can calculate the absolute age of the rock. a rock contains 125 g of a radioisotope with a half-life of 150 000 years and 875 g of its daughter product. how old is the rock according to the radiometric dating method?
