Question:

The percent natural abundance of ⁴⁰K is 0.0117%. The radioactive decay of ⁴⁰K atoms occurs 89% by β^– emission; the rest is by electron capture and β⁺ emission. The half-life of ⁴⁰K is 1.26 x 10⁹ years. Calculate the number of β^– particles produced per second by the ⁴⁰K present in a 1.00 g sample of the mineral microcline, KAlSi₃O₈.
