The half life for the radioactive decay of potassium-40 to argon-40 is 1.26 × 10’ years. Suppose nuclear chemical analysis shows that there is 0.418 mmol of argon-40 for every 1.000 mmol of potassium-40 in a certain sample of rock. Calculate the age of the rock. Round your answer to 2 significant digits. years ?
