(a)
Find the percent of the original C-14 that a scientist can expect to find today .
(a)
Answer to Problem 3E
About 95.3%
Explanation of Solution
Given:
Using tree-ring chronology it is found that 400 years have passed since a given wood sample was part of a living tree.
Formula Used:
Half-life decay formula:
Calculation:
Let
N is the amount of C-14 in the sample discovered ,
So, we need to find
The time passed since the sample was part of living tree = t = 400 years
So,
So, the percent of the original C-14 that a scientist can expect to find today is about 95.3%
(b)
Find the percent of the original C-14 that a scientist can expect to find 200 years from now.
(b)
Answer to Problem 3E
About 92.9%
Explanation of Solution
Given:
Using tree-ring chronology it is found that 400 years have passed since a given wood sample was part of a living tree.
Formula Used:
Half-life decay formula:
Calculation:
Let
N is the amount of C-14 in the sample discovered ,
So, we need to find
The time passed since the sample was part of living tree , 200 year from now = t = 400+200 = 600 years
So,
So, the percent of the original C-14 that a scientist can expect to find 200 years from now is about 92.9%
