A meteor is found to contain 4g 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.
