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 3.8x10-3 grams of uranium and 2.4x10-5 grams of lead. If the half-life of uranium is 4.41x109 years how old is the rock? Hint: moles U + moles Pb = moles U initially in the sample (Parent)
