Use the following
information to carbon-date the site.
Activity of 1 g of fresh carbon = 0.25 Bq. half-life of carbon-14 = 5730 years.
Homework Answers
Concept - first find the activity of the given sample using the activity of fresh 1 g carbon. Then find the decay constant using the half life of carbon. Then use the equation of activity to find the age of the sample.

A 10.00 g sample of wood from an archaeological site produced 3072 β particles in a 10-hour measurement owing to the presence of carbon-14, while a 10.00 g sample of new wood produced 9216 β particles in the same period of time. The half-life of carbon-14 is 5730 years. How old is the wood from the archaeological site?

The answer is not 13657.8
A piece of charcoal used for cooking is found at the remains of an ancient campsite. A 1.2 kg sample of carbon from the wood has an activity of 1660 decays per minute. Find the age of the charcoal. Living material has an activity of 15 decays/minute per gram of carbon present and the half-life of 14C is 5730 y.
