Explanation:
The disintegration rate, which shows in C-14 atoms =
Rate of sample disintegration =
The digit proportion of C-14 can be determined that is included in the sample
5730 years from half-life.
The number with half-lives (n) which are repelled must be determined:
So, the age of the sample is given by =
