A meteor is found to contain 5g of Pb-206 to every 1.00g of U-238. Assuming that the meteor did not contain any Pb-206 at the time of its formation, determine the age of the meteor. Uranium-238 decays to lead-206 with a half-life of 4.5 billion years. Enter your answer with units of years (this will be a lot of numbers since you can't use scientific notation). Enter with at least 3 sig figs.

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 82.4% of the amount of uranium-238 that it contained when it was formed. (The amount that the rock contained when it was formed can be deduced from the presence of the decay products of U−238.) How old is the rock?

9 Question (1 point) See page 978 Uranium-lead (U-Pb) dating of geological samples is one of the oldest and most refined radiometric dating methods, able to determine ages of about 1 million years to over 4.5 billion years with precision in the 0.1-1% range. The U-Pb dating method relies on two separate decay chains, one of which is the uranium series from 238 to 206Pb, with a half-life of 4.47 billion years. 5th attempt w See Periodic Table See Hint...

Applications of radioactive decay extend beyond potential terrorism. There are a number of regularly used practical applications. One such application is to use radioactive decay as a mechanism for determining the age of a sample of bones, rocks, meteorites, etc. Say you area scientist tasked with analyzing samples of moon rocks. Your moon rock contains small amounts of Uranium-238. U-238 decays into lead-206 with a half-life of 4.5 billion years. How old is your rock if 55.0% of the original...
