Rubidium-87 decays by B production to strontium-87 with a half life of 4.7 x 1010 years. What is the age of a rock sample that contains 101.7 ug 87Rb and 6.8 ug 87Sr ? years old Assume that no 87Sr was present when the rock was formed. The atomic masses are given in the table below: Nuclide Atomic Mass 87RB 86.90919 87Sr 86.90888
