A certain rock contains 2.57 x 1017 atoms of 40k for every 7.71 x 1016 atoms of 40 Ar. Assuming that no argon was in the rock when it solidified and that no argon escaped since its solidification, calculate the age of the rock. The half-life of 40K is 1.3 x 10 years. 2.57 years 4.9 x 108 years 1.77 years 2.49 x 10 years
