Answer:
2.04 moles of C atoms
Step-by-step explanation:
The number of moles of C atoms can be calculated using Avogadro's number, which is approximately 6.02 x 10^23 atoms per mole.
To find the number of moles of C atoms in 1.23 x 10^24 atoms, we need to divide the number of atoms by Avogadro's number:1.23 x 10^24 atoms / 6.02 x 10^23 atoms/mole = 2.04 moles
Therefore, if you have 1.23 x 10^24 atoms of C, you would have 2.04 moles of C atoms.
