Question

times the Carbon-14 activity of living plants. What is the age of the sample in years? (The half-life of the Carbon-14 isotope is 5730 years.) Tries 0 / 20

Answer 1

The formula to calculate the age of a plant from Carbon-14 activity is

Age= ln(A/Ao)/-k
In this formula, "A" is the sample's carbon-14 activity
"Ao" is the background carbon-14 activity for this area of the Earth
"k" is the rate at which carbon-14 decays with time, which is -0.00015 (this is the same as 5730)

The age of the sample calculated from the formula is 3700 years
