half life U-235 is 7.04x10^8 years half life U-238 is 4.468 x10^9 years 3. One may assume that when U-238 was formed at the genesis of Earth, an equal amount of 235U was formed. Today the amount of 238U is 138 times the amount of 235U. How long a time ago did the genesis occur according to this assumption?

A moon rock collected by a U.S. Apollo mission is estimated to be 4.30 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 200 Pb in the rock, if it currently contains 1.470 g of 238U? The half-life of 238 U is 4.47 x 10 years 0 206Pb mass:0.4
