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.

0.0102 g

Explanation:

A common formula for determining the amount of sample remaining in terms of its half-life is

where

t = 50 000 yr

      Calculate n

n = 50 000/5730

n = 8.726

===============

N₀ = 4.30 g                       Calculate N

N = 4.30 × 2.36 × 10⁻³

N₀ = 0.0102 g

i will, dm me on here.

i need some with some bio stuff see if anyone will
