Curious to know the age of the fossil, she takes the rock to a lab. The lab determines the amount of rubidium (Rb) and strontium (Sr) in the rock. The scientist is familiar with radiometric dating and knows that she can now calculate the age of the rock, 1, using an isochron. The Rb-Sr isochron equation is 87. Rb. [edr – 1] 86 °Sr. 87 87 Sro 86 Sro 86 Sr. 87. Rb 3.807 and 89.60. In a published table, she finds that Using the lab's values, she calculates the isotope ratios as 86 Sr. 87 = 0.7129. She also finds that the decay constant, 86 the ratio of strontium-87 to strontium-86 at the formation of the rock was Sro 2, for rubidium-87 is 1.42 x 10-11. Use the equation and provided data to calculate t. Put your answer in scientific notation and round to the nearest tenth. years x10 What is the approximate age of the rock in billions of years?
