ass spectrometric analysis of Potassium and Argon atoms in a Moom ock sample shows that the ratio of the number of (stable) 40Ar atoms resent to the number of (radioactive) 4K atoms is 11. Assume that a e argon atoms were produced by the decay of Potassium atoms, with half-life of 1.25 x 10⁰ years. How old is the rock?
