The half-life of Carbon-14 is 5730 years. Suppose a fossil is found with 50% of Carbon-14 as compared to a living sample. How ol
nata0808 [166]

Answer:

5732 years

Explanation:

Radioactive decay can be determined by using the equation:

N_t = N_0e^{- \lambda t}

where;

N_t = number of decayed atoms at time (t)

N_0 = initial number of decayed atoms

\lambda = decay constant

So, if we equate the natural log of the above; we have:

In(N_t) = In(N_0)-\lambda t

\frac{In(N_t)} { In(N_0)}} = -\lambda t

where;

\lambda = \frac{0.693}{t_{1/2}}

\lambda = \frac{0.693}{5730}

\lambda = 1.209*10^{-4

In(\frac{50}{100}) =-(1.209 *10^{-4})*t

-0.693 = -(1.209*10^{-4})*t

t= \frac{0.693}{1.209*10^{-4}}

t = 5732.01 years

t = 5732 years.

Hence, the fossil is 5732 years old.
