Carbon 14 (14c) dating assumes that the carbon dioxide on Earth today has the same radioactive content as it did centuries ago. If this is true, the amount of 14c absorbed by a tree that grew several centuries ago should be the same as the amount of 14c absorbed by a tree growing today. A piece of ancient charcoal contains only 20% as much radioactive carbon as a piece of modern charcoal. How long ago was the tree burned to...

thank you for the help. The half-life of carbon-14 is 5600 years. If a piece of charcoal made from the wood of a tree shows only 74% of the carbon-14 expected in living matter when did the tree die? The tree died about years ago (Do not round until the final answer Then round to the nearest whole number.)

1. An archaeologist conducting a dig in New Mexico discovers some ancient bones. radiocarbon analysis indicates that 0.249 of the original amount of carbon-14 is left a. approximately how many half-lives have elapsed/passed b.if the single half-life value for carbon-14 is 5730 years, approximately how old are the remains?

Carbon-14 is a radioactive isotope of carbon with a nucleus containing 6 protons and 8 neutrons. Its presence in organic materials is the basis of the radiocarbon dating. The half-life of carbon-14 is 5,730 years. If a fossilised tree trunk originally contained 8 nanograms of C-14, how long will it take for the C-14 to decay to 1 nanogram
