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
