WebMar 23, 2024 · The half-life of this isotope is 10 days. Solution To determine the number of half-lives (n), both time units must be the same. 720hours × 1day 24hours = 30days n = 3 = 30days 10days how much mass remains = 1 23(8.0ug) After 720 hours, 1.0 ug of the material remains as Ac -225 Radioactive Dating WebWe can use the half life of the substance to do this. The half life of Bismuth-210 is 5 days. This says that after t = 5, the original population of 800 mg has decay to half of its original amount, or (800) 400 2 1 = mg. Mathematically, since P(t) represents that amount of population of the substance left after time t, this says that P(5) =400 ...
