The ratio of 14C to 12C in living organisms is 1.3 × 10-12. The fossilized remains of an organism are discovered and the ratio of 14C to 12C in the fossil is measured to be 2.8 × 10-13. How long ago, in years was the organism alive? (The half life of 14C is 5,730 years.)

If you answer could you please show all steps on how to find the answer?

Thank you so much for your time and help!

Carbon Dating: All living organisms contain two isotopes (types) of carbon; carbon-12 ( 12C) and carbon-14 (14C). Carbon-12 is stable, meaning that its atoms do not decay. Carbon-14 however, is radioactive or unstable, meaning that an atom of carbon-14 may decay. It does this by throwing off an electron and thus transforming itself into Nitrogen 14. The ratio of carbon-14 to carbon-12 is the same for all living organisims, about 1/10, 000. However, once an organisim dies the carbon-14 begins...

Cosmic rays knock neutrons out of atomic nuclei in the upper atmosphere. Displaced neutrons hit ordinary nitrogen (14N) at lower altitudes, converting it into 14C. Unlike common carbon (12C), 14C is unstable and slowly decays, changing it back to nitrogen and releasing energy (radioactivity). Living organisms turn atmospheric carbon into tissue with the same ratio 14C/ 12C as in the atmosphere (1 in a trillion). How is this process utilized to determine the age of organic items that are less...
