Answer:
A
(
t
)=0.659 gram of C-14
Explanation:
Mathematically exponential decay can be expressed as
where
A
(
t
) - the amount left after t years;
A
0 - the initial quantity of the substance that will undergo decay;
t
1/2 - the half-life of the decaying quantity.
Calculation:
Given that
A
0 =2700 gram sample of C-14
t=time=12 times of half life of C-14
Required data:
A
(
t
)=?
Putting value in the attached equation we get
A
(
t
)=0.659 gram of C-14
