Final answer:
There are approximately 3.31 × 10^24 atoms of palladium in 5.49 mol.
Step-by-step explanation:
To calculate the number of atoms in a given amount of a substance, you need to use Avogadro's number, which is 6.022 × 10^23 atoms/mol. In this case, you have 5.49 mol of palladium (Pd). Simply multiply the number of moles by Avogadro's number:
Number of atoms = 5.49 mol * (6.022 × 10^23 atoms/mol) = 3.31 × 10^24 atoms
Therefore, there are approximately 3.31 × 10^24 atoms of palladium in 5.49 mol.
