If an organism had 200 atoms of carbon-14 at death, how many atoms will be present after 14,325 years? Round the answer to the nearest hundredth.
Answer:
35.34 atoms will be present after 14,325 years.
Step-by-step explanation:
Given : Carbon-14 has a half-life of approximately 5,730 years. This exponential decay can be modeled with the function N(t) = N0. If an organism had 200 atoms of carbon-14 at death.
To find : How many atoms will be present after 14,325 years?
Solution :
The half-life exponential function modeled is \(N=N_o(\frac{1}{2})^{\frac{t}{h}}\)
Where, \(N_o=200\) is the initial atoms
N is the total number of atoms.
t=14,325 years is the time
h=5,730 years is the half-life time
Substitute the value in the formula,
\(N=200(\frac{1}{2})^{\frac{14325}{5730}}\)
\(N=200(\frac{1}{2})^{2.5}\)
\(N=200(0.1767)\)
\(N=35.34\)
Therefore, 35.34 atoms will be present after 14,325 years.
