You are given a rock that contains some zircons. When you measure the amount of uranium and lead in the zircons you find out that the zircons contain 325 atoms of Uranium-238 (the parent isotope) and 2275 atoms of Thorium-234 (the daughter isotope). If Uranium-238 has a half-life of 4.5 billion years, how old are the zircons? Does this answer make sense? Explain your reasoning.
