WitrynaSolution. We use the equation A t = ( 1 2) t t 1 / 2 A o, where A t is the activity in time t, A o is the original activity. 500 = ( 1 2) 10 t 1 / 2 × 6000. t 1 / 2 = 10 log 2 log 12. = 2. 789 h o u r s. We can also use the relation A t = ( 1 2) n A o, where n is the number of half-lives. A t = A o 2 n. n = t t 1 / 2 = l og A o A t log 2. WitrynaUsing exponential decay equation to solve for relationship between k and half-life. Using semi-log plot to get graph of a straight line with slope of -k. ... this would represent the number of radioactive nuclei. Let's do it for half-life. So remember, when half-life-- when time is equal to a half-life, right, the number of radioactive nuclei ...
