Question 605661
An artifact was found and tested for its carbon-14 content. If 72% of the original carbon-14 was still present, what is its probable age (to the nearest 100 years)? Use that carbon-14 has a half-life of 5,730 years
**
Formula for carbon 14 dating:
age of artifact=ln(carbon 14 present)* half-life/rate of decay
=ln(.72)*5730/-.693
≈2700 years
