Expert Answer 100% (1 rating) 1st step All steps Final answer Step 1/2 The geochronometrical equation for the rubidium-strontium dating system is: t = (1/λ) ln [1 + (87Rb/86Sr)] View the full answer Step 2/2 Final answer Radiometric dating has been carried out since 1905 when it was invented by Ernest Rutherford as a method by which one might determine the age of the Earth. In the century since then the techniques have been greatly improved and expanded. Dating can now be performed on samples as small as a nanogram using a mass spectrometer. The mass spectrometer was invented in the 1940…
