Question

What is the half-life of Carbon-11 if the decay constant is 5.68x10^-4/s?

Answer 1

The half-life is related to the decay constant by the formula:

`t_{(1)/(2)}=(\ln2)/(\lambda)`

where λ is the decay constant. Plugging the decay constant given we have:

`t_{(1)/(2)}=(\ln2)/(5.68*10^(-4))=1220`

Therefore, the half-life of Carbon-11 is 1220 s
