There are $3.3 \times 10^{23} atoms$ $3.3 xx 10^23 "atoms"$ in 0.54 moles Pb.

Explanation:

To calculate the number of atoms in Pb, we use Avogadro's number, which is $6.02 \times 10^{23} atoms/mole$ $6.02 xx 10^23 "atoms/mole"$ .

$0.54 mol Pb (\frac{6.02 \times 10^{23} atoms Pb}{mol Pb})$ $0.54 "mol Pb"((6.02xx10^23 "atoms Pb")/"mol Pb")$

$= 3.3 \times 10^{23} atoms Pb$ $=3.3xx10^23 "atoms Pb"$
