Question
14/6 c has a half-life of 5600 years. An anyalsis of charcoal from a wood fire shows that 14c content is 25 per cent of living wood.
how many years have passed since fire for the wood was cut
how many years have passed since fire for the wood was cut
Answers
k = 0.693/t<sub>1/2</sub>
Substitute the value of k into the below equation.
ln(No/N) = kt
No = 100
N = 25
k from above
Solve for t in years.
