Suppose a laboratory has a 31 g sample of polonium-210. The half-life of polonium-210 is about 138 days. How many half-lives of polonium-210 occur in 966 days? How much polonium is in the sample 966 days later?
Answered by Steve
966/138 = 7

7 half-lives means that 1/128 of the original 31g remains.
