Problem

Rubidium-87 decays by β-particle production to strontium-87 with a half-life of 4.7 X 1010 years. What is the age of a rock sample that contains 109.7 ug of  87Rb and 3.1 ug of  87Sr? Assume that no 87Sr was present when the rock was formed. The atomic masses for   87Rb and 87Sr are 86.90919 u and 86.90888 u, respectively.
