It … WebThe other half have deteriorated or decayed after another half life, we have 25 Adams and then after another half life, we're down 12.5. So that just matches are 1/8. 1/8 of 100 is 12.5 Adams. And so how maney half lives had to pass. Before that, we got to 12.5 being countem up 123 So there were 3/2 lives.

WebThe half - Life period is given as λ l n ( N 0 / 2 N 0) = − λ t 1 / 2 ⇒ λ t 1 / 2 = l n 2 λ Calculation: Now, Given value of half life period = 1600 years Also, we have the expression of half-life as λ t 1 / 2 = l n 2 λ -- (1) The radium existing Now N 0 = 100 gm The radium remained N = 25 gm So, we have N = N 0 / 4 λ l n ( N 0 / 4 N 0) = − λ t ' WebIf the half-life of radium is 1,600 y, how long before the sample’s activity is 1.0 mCi?
