Explanation:
From Avogadro's hypothesis, we understand that 1mole of a substance contains 6.02x10^23 atoms.
From the above, it is evident that 1mole of Pb will also contain 6.02x10^23 atoms.
1mole of Pb = 207g/mol
207g of Pb contains 6.02x10^23 atoms.
Therefore, Xg of Pb will contain 1.2044 x 10^24 atoms i.e
Xg of Pb = (207x1.2044x10^24)/6.02x10^23 = 414.14g
