Reams are used to give large quantities.
A ream is equivalent to 500 atoms.There are 3 x 10¹⁸ reams of Pb.
Since 1 ream is equivalent to 500 atoms,
Then 3 x 10¹⁸ reams of Pb contains - 500 x 3 x 10¹⁸ atoms
= 1500 x 10¹⁸ atoms
Therefore total number of Pb atoms are - 1.5 x 10²¹ Pb atoms

Answer : The number of atoms of lead are [tex]1.5\times 10^{21}[/tex]
Explanation :
As we know that, 1 ream is equivalent to 500 atoms.
1 reams = 500 atoms
Now we have to determine the number of lead atoms.
As, 1 reams of lead = 500 atoms of lead
So, [tex]3.00\times 10^{18}[/tex] reams of lead = [tex]3.00\times 10^{18}\times 500=1.5\times 10^{21}[/tex] atoms of lead
Therefore, the number of atoms of lead are [tex]1.5\times 10^{21}[/tex]
