WebAug 8, 2024 · We can determine the amount of a radioactive isotope remaining after a given number half-lives by using the following expression: amount remaining = initial amount × (1 2)n where n is the number of half-lives. This expression works even if the number of half-lives is not a whole number. Example 11.5.1: Fluorine-20 WebJan 30, 2024 · A We can calculate the half-life of the reaction using Equation 3: t 1 / 2 = 0.693 k = 0.693 1.5 × 10 − 3 min − 1 = 4.6 × 10 2 min Thus it takes almost 8 h for half of the cis-platin to hydrolyze.
