The molar mass of lead (Pb) is 207.2 g/mol. To calculate the number of moles of lead in 1.00 lb of lead, we need to convert the mass to grams and then divide by the molar mass.
1.00 lb = 453.592 g
Number of moles of lead = 453.592 g / 207.2 g/mol
Number of moles of lead = 2.19
Therefore, there are 2.19 moles of atoms in 1.00 lb of lead.
