Please help ASAP I'm stuck!!!

create an imaginary example of finding a given amount of Lokium and DOL in a rock, and then determining the absolute age of that rock. Assume that each trial represents 1,000 years.

  1. Figure out what percentage of the original mass of whatever (Lokium?) is left. The link below shows you how to proceed if it were carbon 14
    The idea is that amount = original amount * (1/2)^n
    where n is the number of half lives it has decayed
    if
    x = Xo * (1/2)^n
    then
    fraction = x/Xo = (1/2)^n
    ln (fraction) = n ln (1/2) = -.693 n
    then fraction = e^(-.693 n)
