3.25 X 10^20 atoms lead (1 mole lead/6.022 X 10^23)
= 5.40 X 10^-4 moles lead
There are 2.49 x 10^-12 moles of lead in that sample.

(2.16x10^24 atoms) x ( 1 mole/ 6.022x10^23 atoms) = 0.3586848223x10^1 which your answer should be 3.59 moles
44 moles of atoms
How many moles of atoms are contained in 382 g Co
Atomic mass: 207.2 grams.455 moles × (6.02 × 1023) = 2.74 × 1023 atoms of lead
There are 2.49 x 10^-12 moles of lead in that sample.
