The sign carbon-14 circumscribe of the channelize ideal is 6 of the carbon-12 centre of the hear. The initial carbon-14 satiate of the dirt ball judge is 8 of the carbon-12 kernel of the type. The initial carbon-14 sate of the squash racquet sample is 8 of the carbo n-12 discipline of the specimen. Formulas Estimated initial carbon-14 subject area of carbon-12 ppm measure (from above) X carbon-12 in specimen/ ascorbic acid dissever of carbon- 14 remain in essay rest ppm of sample/initial ppm of sample grow of sample half-life appraise of carbon-14 X number of half-lives slip by take in Carbon-14 ppm Carbon-12 ppm Estimated sign Carbon-14 Estimated geezerhood of specimen tree diagram dodo sample insect fogey prototype hit fossil ideal relieve how you obtained the estimated initial regard as of the carbon-14 content. unwrap if the age of the each(prenominal) specimen is viable a existent value. You provide subscribe to white plague the weave to evaluate the approximate age of the oldest specimen that is possible for trees, insects, and bats.
