A sample of radon-222 has a half-life of 3.8 days. If you start with 100g, how much remains after 15.2 days?
💡 Hint: Count how many half-lives fit into 15.2 days and apply them successively.
If a radioactive isotope has a decay constant of 0.04 per month, calculate its half-life.
💡 Hint: Use the natural logarithm to find the half-life from the decay constant.
