A moon rock collected by a U.S. Apollo mission is estimated to be 4.00 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 in the rock, if it currently contains 1.245 g of 238U? The half-life of 238 U is 4.47 x 109 years. 206 Pb mass: x10 TOOLS g
