An archaeological artifact containing wood had only 80% of the 14C found in a living tree. Estimate the age of the sample. Hence, the age of the sample is 1845 years.

## What is the half-life of carbon-14 is 5730 years?

approximately 5730 years The half-life of Carbon 14, that is, the amount of time it takes for half of any amount of Carbon 14 to decay, is approximately 5730 years. Suppose we have a preserved plant and that the plant, at the time it died, contained 10 micrograms of Carbon 14 (one microgram is equal to one millionth of a gram).

## How old is the sample if the half-life of carbon-14 is 5730 years hint how many half lives does it take to get to 1/16 of the original amount?

So, your answer would be the time it takes for carbon-14 to elapse 3 half-lives.

## What does it mean to say that the half-life of carbon-14 is 5730 years?

Carbon-14 has a relatively short half-life of 5,730 years, meaning that the fraction of carbon-14 in a sample is halved over the course of 5,730 years due to radioactive decay to nitrogen-14.

## What percentage of carbon 14 remains after 3 half lives?

After 3 half-life, 12 of the 14 of the C-14 = 18 of the C-14 would remain. After n half-lives, 12n of the C-14 would remain.

## What percentage of C-14 remains after 3 half lives?

After 1 half-life, 12 of the C-14 would remain. After 2 half-life, 12 of the 12 of the C-14 = 14 of the C-14 would remain. After 3 half-life, 12 of the 14 of the C-14 = 18 of the C-14 would remain.
