The level of thorium in a sample decreases by a factor of one-half every 2 million years. A meteorite is discovered to have only 8.6% of its original thorium remaining. How old is the meteorite?Answer by scott8148(6628)   (Show Source): You can put this solution on YOUR website!the half-life equation is ___ .086 = (1/2)^(t / 2000000) ___ t is the time (age) taking logarithm ___ log(.086) = log(1/2) * (t / 2000000) [log(.086) / log(1/2)] * 2000000 = t = 7,080,000 (approx)
