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.
