Question 7 1 pts The AC activity of an artifact from a burial site was 8.7/min.g C. The half-life of C is 5730 years, and the current activity is 16.1/min.g C (that is, 16.1 disintegrations per minute per gram of carbon). How old in years) is the artifact? Enter number to 1 decimal place. Question 8 1 pts Analysis of an ant found in a piece of amber provided 10 disintegrations of 14C/min.g C, whereas...

A wooden artifact is found to have a 14C activity of 6.1 disintegrations per second. Given that the 14C activity of an equal mass of fresh-cut wood has a constant value of 15.2 disintegrations per second, determine the age (years) of the artifact. The half-life of carbon-14 is 5715 years.
Mass of carbon in animal bone fragment found in an archeological site is 198g. If the bone registers an activity of 16 decays/s from radioactive 14C. What is its age?. Assume that the animal when it died that the ratio of 14C to 12C was 1.3x10-12. The half-life of 14C is 5730years.

The half-life of carbon-14 is 5,730 years. An artifact produces 9.9 disintegrations of 14C per minute per gram of carbon in the sample. Estimate the age of this sample assuming that its original radioactivity was 15.3 disintegrations per minute per gram of carbon.
Living matter has a carbon-14 activity of about 24.0 counts/min per gram of carbon. What is the age of an artifact for which the carbon-14 activity is 3.00 counts/min per gram of carbon?

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.
The half-life of 14C is 5730 years. The activity of carbon in living being is 12.5 counts per minute per gram of carbon. Calculate the activity of carbon from the remains of an organism that died 50,000 years ago.
