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 20Pb in the rock, if it currently contains 1.375 g of 2U? The half-life of 2U is 4.47 x 10° years. 20pb mass:
