4.14 The half-life for radioactive decay of is 5730 years. An archaeological artifact containing wood had only 80% of the 14C found in a living tree. Estimate the age of the sample.
half-life of radioactive decay = 5730 years
we know that, for first-order reaction,
= 1845 years (approximately)
Thus, the age of the sample is 1845 years
