A moon rock collected by a U.S. Apollo mission is estimated to be 3.80 billion years old by uranium/lead dating. Assuming that the rock did not contain any lead when it was formed, what is the current mass of ^206 Pb per 1.135 g of ^238 U in the rock? The half-life of ^238 U is t_v2 = 4.47 times 10^9 years. Number ________ g
