A rock was recently discovered near the arctic circle (just a little east of Barrow, Alaska) which was found to contain 1.0239 nanograms (ng) of 206Pb and 2.6556 ng of 238U. The decay series of 238U to 206Pb is a process which has a half-life of 4.50x109 years. We assume the first step in this decay series is, by far, the slowest and that all the 206Pb found in the sample is derived from this decay process. How old (in billions of years, where 1 billion = 109) is the rock
