Unformatted text preview: 8. (a) Using Eq. 43-19 and adapting Eq. 43-20 to this sample, the number of fission-events per second is (b) Since R ∝ 1 T1/2 = N ln 2 Msam NA ln 2 = T1/2 fission MU T1/2 fission = Rfission (1.0 g)(6.02 × 1023 /mol) ln 2 = 16 fissions/day . (235 g/mol)(3.0 × 1017 y)(365 d/y) (see Eq. 43-19), the ratio of rates is Rα Rfission = T1/2 fission 3.0 × 1017 y = = 4.3 × 108 . T1/2 α 7.0 × 108 y ...
