When radon decays, it becomes polonium and yields a first-order rate law. If the rate constant is 0.175 days^-1 and you begin with a 8.64 g sample of radon:
(a) How much will be left after 2.96 days?
(b) How much will be left after 46.4 hours?
(c) What is the half-life of radon?
(d) How many grams of radon will be left after 5 half-lives?
