If the amount of the parent isotope in the original sample of a rock had been 48 grams,about how much would have been left after three half-lives?2. A parent isotope has a half-life of 500 000 years. If a rock contained 10 mg of the parent isotope whenit formed, how much parent isotope would be left after 1.5 million years?3. A sample of wood from an Egyptian mummy case taken from an archaeological site is subjected toradiocarbon dating. The activity due to 14C has a specific activity of 10.41 d/min.g. The activity of acarbon sample of equal mass from fresh wood is 16.3 d/m.g. How old is the case?4. The remnants of an ancient fire in a cave in Africa showed a C decay rate of 3.9 counts per minuteper gram of carbon. If the decay rate in C-14 in freshly cut wood, is 13.6 counts per minute per gramof carbon, how many years ago did the campfire occur?5. A rock contains 0.257 mg of Pb-206 for everv milligram of U-238.The half-life for the decay of U-238to Pb-206 is 4.5 x 10°. How old is the rock?

#4. The remnants of the ancient fire in a cave in Africa showed a 14C6 decay rate of 3.9 counts…
