• D. 1.2 × 10^{22} atoms

Answer: (B)

Verified step by step guidance

1. Recall that 1 mole of any substance contains Avogadro's number of particles (atoms, molecules, etc.), which is approximately \$6.022 \times 10^{23}$ particles per mole.
2. Identify the given quantity: you have 1.2 moles of carbon atoms.
3. To find the total number of atoms, multiply the number of moles by Avogadro's number using the formula: \(\text{Number of atoms} = \text{moles} \times 6.022 \times 10^{23}\).
4. Substitute the given values into the formula: \(\text{Number of atoms} = 1.2 \times 6.022 \times 10^{23}\).
5. Perform the multiplication to find the total number of carbon atoms present in 1.2 moles.
