Final answer:
There are 4.07 x 10^24 atoms in 6.755 moles of lead.
Step-by-step explanation:
One mole of lead contains 6.022 x 1023 atoms. To find the number of atoms in 6.755 moles of lead, we can use the Avogadro's number, which is 6.022 x 1023 atoms/mol.
Number of atoms = 6.755 moles x (6.022 x 1023 atoms/mol)
Number of atoms = 4.07 x 1024 atoms
