Chemistry: Asample of wood from the remains of a ship was found to contain 40.0% of c-14 as of ordinary wood found now. if the half-life period of c 14 is 5770 years, find the number of years elapsed. (round your answer to the nearest whole number)

Cr.Cr is the only element listed that is located in the d-block of the periodic table....

Explanation:

Carbon-14 is radioactive and it follows the first-order kinetics for a radioactive decay. The first-order kinetics may be described by the following integrated rate law:

$ln(\frac{[A]_t}{[A]_o})=-kt$

Here:

[A]_t is the mass, moles, molarity or percentage of the material left at some time of interest t;

[A]_o is the mass, moles, molarity or percentage of the material initially, we know that initially we expect to have 100 % of carbon-14 before it starts to decay;
