Problem 81P
An ancient skull has a carbon-14 content of 1.563% of that found in living organisms. How old is the skull?
Step-by-Step Solution:
Step 1 of 2
Solution 81P:
Here, we are going to calculate the old of the skull.
Step1:
Half life period of the carbon-14 is 5730 years
We know,
t1/2 =
k =
=
= 1.209x 10-4 yr-1
Step 2:
We know,
-kt = ln= ln
= -4.15856
=
= 3.43967 x 104 yr
= 34396.7 yr
Thus, the skull is 34396.7 years old.
Note, if we take, -4.159 instead of -4.15856
