Chapter 32, Problem 74GP

Moon Rocks In one of the rocks brought back from the Moon, it Is found that 80.5% of the initial potassium-40 in the rock has decayed to argon-40. (a) If the half-life for this decay is 1.20 × 10⁹ years, how old is the rock? (b) How much longer will it take before only 10.0% of the original potassium-40 is still present in the rock?
