Question

The half-life of the carbon 14 isotope is 5730 years. If there were 4 billion atoms of C-14 in a particular organism at the time it died, how many atoms of C-14 would there be in the remains of that organism 11,460 years after it died?

Answer 1

Answer:

1 billion

Explanation:

The computation of the number of atoms for C-14 is shown below:

Because it is mentioned

Half the isotope for carbon 14 is 5,730 years

Currently if there had been 4 billion it would equate to 2 billion

Now that the 2 billion would've been 1 billion in the next 5,730 years

And it'll become 3 half-life

Therefore the number of C-14 atoms is 1 billion
