Question 1077862: In 1991, hikers in the Tyrolean Alps of Europe made a remarkable discovery. They found an
almost perfectly preserved body of a prehistoric man, whom scientists named Ötzi. Carbon
dating of samples from the site established the time of Ötzi’s demise at approximately 5,300
years ago. What percentage of the original carbon-14 in Ötzi’s body was remaining in 1991? Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! C14 has a half-life of 5730 years
that means that we can find k
(1/2)=e^(-k*5730)
-0.693=-5730k
k=0.00012
fraction=e^(-5300*k)=e^(-0.6401)=0.5267
52.67%
