A moon rock collected by a U.S. Apollo mission is estimated to be 4.20 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 206Pb in the rock, if it currently contains 1.360 g of 238 U? The half-life of 238U is 4.47 x 10° years. 206Pb mass: g
