Answer: approximately 0.0556atoms of 14C

Explanation:

Since 1000atoms of 14C was presently found in the atom that was created 18000years ago. The number of atoms of 14C that will be in that object when it was made will be 1000/18000 which is 0.0556atoms of 14C.

Note that the number of atoms present in it 18000years ago will be a way smaller than present atoms of 14C in it
