A piece of wood was found to have .^(14)...

A piece of wood was found to have `.^(14)C//^(12)C` ratio `0.6` times that in a living plant. Calculate the period when the plant died (Half-life of `.^(14)C=5760` years)

Text Solution

Verified by Experts

`t=(2.303xxt_(1//2))/(0.693)xxlog((N_(0))/(N))`
`=(2.303xx5760)/(0.693)xxlog((1)/(0.6))`
`=(2.303xx5700)/(0.693)xx0.2201=4213` years
