Rb-87 decays with a half-life of 48.8 billion years to Sr-87. For short periods of time, there are so few decays that the number of changed nuclei is far smaller than the experimental error. The current limit on object ages therefore is 100,000,000 years or older. What is the percentage of Rb-87 left after 100,000,000 years?
