Imagine you collected a volcanic rock while on vacation to Hawaii and you want to know how old it is. Suppose a laboratory that analyzes your rock and tells you that there are 4 micrograms of Uranium-234 (parent) and 124 micrograms of Thorium- 230 (daughter) in your sample. Given that the half-life of this isotope pair is 245 million years, how old is your rock?
