Question

A fossil is found to have a 14 C level of 64.0 % compared to living organisms. How old is the fossil?

Answer 1

Answer: the answer is 3605 years old

Explanation: the explanation is in attached documents

Answer 2

3689 years

Step-by-step explanation:

The amount of fossil = 64.0% compare to living organism = 0.64

The number of half life elapsed =
`((1)/(2))^n=0.64`

`(0.5)^n =0.64`

`nlog0.5=log(0.64)`

`(-0.1938)/(-0.30102)`

`= 0.643811`

n= 0.6438

However, the age of the fossil = half life of C-14 × number of half life elapsed

= 5730 × 0.6438

= 3689 years
