Question

Urgent!!!

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(1/2)^t/T .


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

Answer 1

0.0102 g

Step-by-step 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
