Answer:
4066 decay/s
Explanation:
Given that:-
The weight of the person is:- 190 lb
Also, 1 lb = 453.592 g
So, weight of the person = 86182.6 g
Also, given that carbon is 18% in the human body. So,
Carbon-14 is of the carbon in the body. So,
Also,
14 g of Carbon-14 contains atoms of carbon-14
So,
of Carbon-14 contains atoms of carbon-14
Atoms of carbon-14 =
Given that:
Half life = 5730 years
Where, k is rate constant
So,
The rate constant, k = 0.00012 years⁻¹
Also, 1 year = s
So, The rate constant, k = s⁻¹ =
Thus, decay events per second = = = 4066 decay/s
