3.25 X 10^20 atoms lead (1 mole lead/6.022 X 10^23)
= 5.40 X 10^-4 moles lead
To find the number of moles of atoms in 1.00 lb of lead, you would first convert the weight to grams (1 lb = 453.592 grams), then divide by the molar mass of lead (207.2 g/mol). This calculation would give you the number of moles of lead atoms in 1 lb of lead, which is approximately 2.19 moles.
(2.16x10^24 atoms) x ( 1 mole/ 6.022x10^23 atoms) = 0.3586848223x10^1 which your answer should be 3.59 moles
To determine the number of moles of lead in 1.50 x 10^12 atoms, you can use Avogadro's number, which is 6.022 x 10^23 atoms/mol. First, calculate the number of moles by dividing the number of atoms given by Avogadro's number. ( \frac{1.5 \times 10^{12}}{6.022 \times 10^{23}} = 2.49 \times 10^{-12} ) moles of lead.
To find the number of atoms in 0.23 g of lead (Pb), you first need to determine the number of moles using the molar mass of lead. Lead has a molar mass of approximately 207.2 g/mol. Then use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms.
There are twice as many oxygen atoms as carbon atoms in carbon dioxide, so 100.0 moles of carbon dioxide would contain 200.0 moles of oxygen atoms.
Atomic mass: 207.2 grams.455 moles × (6.02 × 1023) = 2.74 × 1023 atoms of lead
To find the number of moles in 2.16 x 10^24 atoms of lead, you would divide the number of atoms by Avogadro's number, which is 6.022 x 10^23 atoms/mol. Thus, 2.16 x 10^24 atoms of lead is equal to 3.59 moles.

To find the number of lead atoms in 4.001018 reams of lead, you first need to convert the number of reams to moles using the molar mass of lead. Then, use Avogadro's number (6.022 x 10^23) to convert moles of lead to lead atoms.
1,638 moles contain 9,864266723766.10e23 atoms.
20 moles
6.747 moles of lead (6.022 X 10^23/1 mole Pb) = 4.063 X 10^24 atoms of lead
This is equivalent to 1,4 moles.
