Carbon-14 is a radioactive isotope used to determine the age of samples of organic matter. The amount of carbon-14in a sample decreases once the organism is no longer alive. The half-life of carbon-14 is approximately 5730 years. This means that every 5730 years, the amount of carbon-...
The bones from an animal found at an archaeological dig have a c614 activity of 0.10 bq per gram of carbon. The half-life of c614 is 5730 yr. What is the age of the bones? The amount of carbon-14 still present in ...
