Type the correct answer in the box. express your answer to three significant figures.

the half-life of carbon-14 is 5,730 years. dating organic material by looking for c-14 can’t be accurately done after 50,000 years.

suppose a fossilized tree branch originally contained 4.30 grams of c-14. how much c-14 would be left after 50,000 years?

use the formula n = n0 .

a tree branch that originally had 4.3 grams of carbon-14 will have
grams after 50,000 years.
