The carbon-14 in the fossil had five half-lives.

Carbon-14 is a radioactive nucleus with a half-life of 5760 years. In livingmatter the amount of carbon-14 decays at a rate of 15.3 decay events perminute per gram of carbon. A fossil is analysed and found to have a carbon-14 decay rate of 7.70 decay events per minute per gram of carbon. How oldis the fossil?

If a fossil was found that had 50% radioactive carbon-14 and 50% decayed element, approximately how old is the fossil?

The half-life of carbon-14, 14C, is approximately 5,730 years. A bone fragment is estimated to have originally contained 4 milligrams of 14C.Write the exponential decay equation where A is the amount (in mg) of carbon-14 remaining in the bone fragment after t years.

In the process of radiometric dating, if the percent of the original amount of carbon-14 present in a fossil is 12.5%, how old is the fossil? The half-life of carbon-14 is 5,730 years.Multiple choice question.11,460 years old17,190 years old5,700 years old22,920 years old
