Answer:-

5 mol of Lead

3.01 x 10^24 atoms of Lead

Explanation:-

Mass of lead = 1.035 kg x 1000 = 1035 g

Atomic mass of Lead = 207.2 g mol-1

Number of moles of lead = Mass / atomic mass

= 1035 g / 207.2 g mol-1

=5 mol

By Avogadro's Law we know 1 mol of an element has 6.02 x 10^23 atoms

So 5 mol of Lead has 5 x 6.02 x 10^23

= 3.01 x 10^24 atoms of Lead
