The half-life of Potassium-40 (K-40) decaying to Argon-40 (Ar-40) is 1.3 billion years. Suppose an igneous...
The half-life of Potassium-40 (K-40) decaying to Argon-40 (Ar-40) is 1.3 billion years. Suppose an igneous rock contains 105 million atoms of Ar-40 and 15 million atoms of K-40. (Assume here that no Ar-40 was present in the mineral when it formed and that no Ar-40 has escaped since formation). Using the number of half-lives from the previous question, how old is this rock? 2.6 billion years old 5.2 billion years old 3.9 billion years old 1.3 billion years old
