Question:

Concerning the decay of²³²Th described in Exercise 29, a certain rock has a ²⁰⁸Pb/²³²Th mass ratio of 0.25/1.00. Estimate the age of the rock.

Exercise 29

What should be the mass ratio ²⁰⁸Pb/²³²Th in a meteorite that is approximately 2.7 x 10⁹ years old? The half-life of ²³²Th is 1.40 x 10¹⁰ years. One ²⁰⁸Pb atom is the final decay product of one ²³²Th atom.
