Question

The half-life for K-40 to decay to Ar-40 is 1.25 billion years. If a meteorite contains 0.85 units of K-40 to 9.15 units Ar-40, find the decay constant for K-40 and the age of the meteorite?

Step 1

The decay constant (λ) can be calculated using the formula: λ = ln(2) / t1/2 where t1/2 is the half-life of the radioactive isotope. Given that the half-life of K-40 is 1.25 billion years, we can substitute this value into the formula: λ = ln(2) / 1.25 x 10^9 Show more…
