WebOct 1, 2016 · The rock is 41.5 years old. For each half-life, you divide the total amount of the isotope by 2, so "Amount remaining" = "original amount"/2^n, where n = "the number of half-lives". A = A_0/2^n You can rearrange this to A_0/A = 2^n If there were originally 100 atoms, and 75 of the atoms remain, we have 100/75 = 2^n 4/3 = 2^n log(4/3) = nlog2 n = …
WebAmericium-241Half Life. This radioactive substance has a half life of 432.2 years, meaning it takes 432.2 years to decay and reduce to the half of its initial amount. Half Life is the time needed by a decaying radioactive substance to fall to half of its original value.
