Carbon 14 Dating
1. The problem statement, all variables and given/known data
The amount of 14C in an old, isolated sample of vegetation is 0.692 that expected from a present day sample with an equivalent carbon content. Calculate the age of the old sample in years.
2. Relevant equations
Im fairly sure you use the following equation to solve this...ln(N/Nsub0)=-.693t/tsub(1/2) ...I could be wrong, because every time I attempt to use it nothing happens haha.
3. The attempt at a solution

No = original amount of radioactive material
N = amount of amout of radioactive material remaining after t
t = time intercal
T =half life
