The rubidium isotope 87 Rb is a ? emitter with a half life of 4.9 × 10^10 y that decays into 87 Sr. It is used to determine the age of rocks and fossils. Rocks containing the fossils of early animals contain a ratio of 87 Sr to 87 Rb of 0.09. Assuming that there was no 87 Sr present when the rocks were formed, calculate the age of these fossils. Answer in units of y
