Uranium is radioactive and decays into lead. This process can be used to date rocks. A piece of zirconium was dated using this process and it was found that this rock contained 3.2x103 grams of uranium and 2.2x10-5 grams of lead. If the half-life of uranium is 4.41x10° years how old is the rock? Hint: moles U + moles Pb = moles U initially in the sample (Parent)
