The amount of `""_(6)^(14)C` isotope in a place of wood is found to be one fifth of that present in a fresh piece of wood. Calculate the age of the piece of wood (half-life of `""_(6)^(14)C=5577` year).

Text Solution

Verified by Experts

`t=(2.303)/(lambda)log.(N_(0))/(N)`
`impliest=(2.303xxt_(1//2))/(0.693)log.(N_(0))/(N)`
`=(2.303xx5577)/(0.693)log.(N_(0))/(N_(0)//5)`
`(2.303xx5577)/(0.693)xx0.6989=12.953` years
