Problem

The activity of a fossil bone is measured to be

9.0\,\text{disintegrations}\;\text{min}^{-1}\,\text{g}^{-1}

of carbon, whereas freshly living bone shows

18.0\,\text{disintegrations}\;\text{min}^{-1}\,\text{g}^{-1}

. Assuming a half-life of

5730\,\text{yr}

for

^{14}\text C

, determine the age of the fossil bone.
