Part A Geologists can estimate the age of rocks by their uranium-238 content. The uranium is incorporated in the rock as it hardens and then decays with first-order kinetics and a half-life of 4.5 billion years. A rock is found to contain 82.9% of the amount of uranium-238 that it contained when it was How old is the rock? formed. (The amount that the rock contained when it was formed can be deduced from the presence of the decay products of U – 238.) Express your answer using two significant figures.
