Question 1172771: Please help
The half-life of a radioactive isotope is the time it takes for a quantity of the isotope to be reduced to half its initial mass. Starting with 215 grams of a radioactive isotope, how much will be left after 4 half-lives?
Use the calculator provided and round your answer to the nearest gram. Answer by ikleyn(52803) (Show Source):
grams remains after 1-st half-life period
grams remains after 2-nd half-life period
grams remains after 3-rd half-life period
grams remains after 4-th half-life period
Now use your calculator.
