Assuming that the rock did not contain any lead when it was formed, what is the current mass of Pb206 in the rock, if it currently contains 1.430 g of U238? The half-life of U238 is 4.47×109 years.

A sample of bone is subjected to radiocarbon dating. The current decay rate observed for its carbon-14 content is 11.2 disintegrations per minute per gram of carbon. What is the age (in years) of the bone? The half-life for carbon-14 is 5.73 x 103 yrs, and the decay rate for carbon-14 in living organisms is 14.3 disintegrations per minute per gram of carbon.
Archeologists continue to debate the arrival of the first humans in the Western Hemisphere. Radiocarbon dating of charcoal from a cave in Chile was used to establish the earliest date of human habitation in South America as 8700 years ago. This procedure involves comparing the 14C present in a sample of charcoal to the 14C present in a living tree of the same age. What fraction of the 14C initially present remained in the charcoal after 8700 years? The half-life of 14C is 5730 years. (Write the answer as a number with a decimal.)
The half life for the decay of carbon-14 is 5.73 × 10³ years. Suppose the activity due to the radioactive decay of the carbon-14 in a tiny sample of an artifact made of wood from an archeological dig is measured to be 17. Bq. The activity in a similar-sized sample of fresh wood is measured to be 18. Bq. Calculate the age of the artifact. Round your answer to 2 significant digits. years x10 X
