You want to use radiometric dating to determine the age of a specimen. You use Isotope Z, which has a half-life of 645 years. You measure your sample and find that 1/16 of the original amount of Isotope Z is present. How old is the sample?
Uranium 238 (U-238) has a half-life of 4.5 billion years. Geologists find a rock containing a mixture of U-238 and lead, and they determine that 85% of the original U-238 remains; the other 15% has decayed into lead. How old is the rock?
Radioactive isotopes can be used to find the age of rocks, fossils, or other
artifacts. Carbon-14 has a half-life of 5,730 years. Suppose a sample of
charcoal from a primitive fire pit contains one eighth of its original amount
of carbon-14. How old is the sample? (Give your answer in units of years)
