Element X decays radioactively with a half life of 14 minutes. If there are 490 grams of Element X, how long, to the nearest tenth of a minute, would it take the element to
decay to 123 grams?

Initially 100 milligrams of a radioactive substance was present. after 6 hours the mass had decreased by 4%. if the rate of decay is proportional to the amount of the substance present at time t, find the amount remaining after 24 hours. (round your answer to one decimal place.)
