A certain moon rock was found to contain equal numbers of potassium and argon atoms Assume that all the argon is the result of radioactive decay of potassium (its half life is about 1 28 x 10 9 years) and that one of every nine potassium atom disintegrations yields an argon atom What is the age of the rock, measured from the time it contained only potassium

Question: A certain moon rock was found to contain equal numbers of potassium and argon atoms. Assume that all the argon is the result of radioactive

A certain moon rock was found to contain equal numbers of potassium and argon atoms. Assume that all the argon is the result of radioactive decay of potassium (its half-life is about 1.28 x 10⁹ years) and that one of every nine potassium atom disintegrations yields an argon atom. What is the age of the rock, measured from the time it contained only potassium?
