WebJul 28, 2024 · Expert Answer. One quick way to do this would be to figure out how many half-lives we have in the time given. 6 days/2 days = 3 half lives 100/2 = 50 (1 half life) 50/2 = 25 (2 half lives) 25/2 = 12.5 (3 half lives) So 12.5g of the isotope would remain after 6 days. Thanks! We're glad this was helpful. WebAll of these radioisotopes are short-lived, the longest-lived being nitrogen-13 with a half-life of 9.965 (4) min. All of the others have half-lives below 7.15 seconds, with most of these being below 620 milliseconds.
