Question

1. You find a piece of cloth painted with organic dyes. An analysis of the dye reveals that only 63% of the carbon-14 origina

Answer 1

Answer #1

If the half-time of the carbon-14 is 5700 years, the full-time will be 11400 years.

If 63% of carbon-14 is remaining in the dye, the age of carbon-14 will also be 63% of the total age.

Age = 0.63*Total age = 0.63*11400 = 7182 years.

The cloth was painted 7182 years ago.

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...

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
