Question
In the lab, it is relatively easy to measure the activity of asample and to estimate the mass of carbon in the sample. From thesemeasurements, it is possible to find the age of the sample.
An artifact is found in a desert cave. Theanthropologists who found this artifact would like to know its age.They find that the present activity of the artifact is 9.25decays/s and that the mass of carbon in the artifact is 0.100 kg.To find the age of the artifact, they will need to use thefollowing constants:
What is the age of the artifact? Express youanswer in years.
Explanation / Answer
Okay, so basically just plug all of the known values into the known equation. The part you should watch out for is units. is given in years, so you need to convert 9.25 decays/s into 291708000 decays/year. You should get something like 6300 when rounded to 4 significant figures.
