A meteor has a Pb-206;U-238 mass ratio of 0.813;1.00. Use the assumptions of Question 41 to estimate the age of the meteor.
Reference
A rock from an archaeological dig was found to contain 0.255 g of Pb-206 per gram of U-238. Assume that the rock did not contain any Pb-206 at the time of its formation and that U-238 decayed only to Pb-206. How old is the rock?
