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
