The amount of C-14 in a sample of wood is 45% of the amount that would be found in a living sample with the same total carbon content.Find the number of years passed since the sample was part of a living tree.

Answer to Problem 1E
6600.96 years
Explanation of Solution
Formula Used:
Half-life decay formula:
Calculation:
Since the amount of C-14 in a sample of wood is 45% of the amount that would be found in a living sample with the same total carbon content So,
Let the time passed since the sample was part of living tree = t
So, the time passed since the sample was part of living tree is 6600.96 years.
