Here's how to determine the moles of each atom in CHCl3 (chloroform):

1. Identify the atoms and their subscripts:

* C (carbon): 1 atom

* H (hydrogen): 1 atom

* Cl (chlorine): 3 atoms

2. Moles in one mole of CHCl3:

* Since the subscripts represent the number of atoms in one molecule, they also represent the number of moles of each element in one mole of the compound.

Therefore:

* Carbon (C): 1 mole

* Hydrogen (H): 1 mole

* Chlorine (Cl): 3 moles
