Answer:D. 2.61 x 10^22
Explanation:
Given that mass of Lead(Pb) = 8.97g
Molar mass of lead =207.2g/mol
No of moles = Mass / molar mass
=8.97g/207.2g/mol
= 0.04329moles
Converting to atoms using Avogadro's number
we know that
1 mole = 6.022 x 1023 atom
Therefore 0.04329 moles of Pb = 0.04329moles x 6.022 x 10^23 atoms
=2.6069 x 10^22
=2.61 x10^22atoms
