How much Cu-60 half-life 24 min would remain from a 4 mg sample after 48 min?
After 48 minutes, two half-lives have passed for Cu-60 (24 min * 2 = 48 min). Each half-life reduces the amount of Cu-60 by half, so after 48 minutes, only 1/4 of the original 4 mg sample would remain, which is 1 mg.
A radioactive sample has a half-life of 5.0 min What fraction of the sample is left after 20 min?
After 20 minutes, there have been 4 half-lives (20 min / 5 min per half-life). Each half-life reduces the sample by half, so the fraction of the sample left after 20 minutes is (1/2)^4, which is 1/16. Therefore, 1/16 of the original sample is left after 20 minutes.
