A moon rock collected by a U.S. Apollo mission is estimated to
be 3.803.80 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 Pb206Pb206 in the rock, if it
currently contains 1.3551.355 g of U238U238? The
half-life
of U238U238 is 4.47×109 years4.47×109 years.
