Solving half life equations
WebTo see how the number of nuclei declines to half its original value in one half-life, let t = t 1/2 in the exponential in the equation N = N 0 e −λt.This gives N = N 0 e −λt = N 0 e −0.693 = 0.500N 0.For integral numbers of half-lives, you can just divide the original number by 2 over and over again, rather than using the exponential relationship. WebC-14 Half-Life = 5730 Years. Solution. We utilize the equation that relate amount remaining, initial mass and number of half-lives,n. N t = 1 2 n X N o = (1 2) 4 X 50 = 3.125 g. 5. What is …
