6) The 87Rb/87Sr method of dating rocks is used in geology. a) Provide the balance reaction for 87Rb changing to 87Sr b) The half-life for this process is 6.0 x 1010 A rock is found to have MOLE ratio of 87Rb to 87Sr of 36:1 How old is the rock? (This is slightly easier than the one done in lecture because the two atoms in that one had different weights.)
