Byron Stevenson · Answer 1

Answer: 414.14g

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
