WebApr 4, 2016 · If we want to determine the number of half-lives n, then we can use the total time passed t and divide by the half-life t1/2. So, we could write this in a more convenient form as. [A] = [A]0(1 2)t/t1/2. Or, in a more universal form, since [A] and [A]0 have the same units, we could easily just call the quantity of the decaying substance as a ...
