• A. 1.41 × 10^{23} atoms
• B. 2.26 × 10^{22} atoms
• C. 2.26 × 10^{23} atoms
• D. 6.02 × 10^{23} atoms

Answer: (C)

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 0.375 moles of palladium (Pd) atoms.
3. To find the 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: \(\text{Number of atoms} = 0.375 \times 6.022 \times 10^{23}\).
5. Perform the multiplication to find the total number of palladium atoms present in 0.375 moles.
