The radioactive isotope XYZ-aaa(aaaXYZ) has a half-life of 6 hours. If 15 milligrams are used, how much will be present after 29 hours? Round the answer to three decimal places.
We'll use the next formula:
N(t) = N0/2^(t/T),
where N0 is initial quantity of a radioactive isotope, T - half-life period. So, there remains
