If you have a 2700 gram sample of C-14 and 12 half-lives have passed how much of your original sample
1 answer:
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
