6.747 moles of lead (6.022 X 10^23/1 mole Pb)
= 4.063 X 10^24 atoms of lead
Pb has a MW of 207.2 g/mol. Thus, 80g of Pb is 80/207.2 = 0.39 mol of lead. Using Avogadro's number: (6.0221415 * 1023 atoms/mol)(0.39 mol) = 2.349 * 1023 atoms.

Pb has a MW of 207.2 g/mol. Thus, 80g of Pb is 80/207.2 = 0.39 mol of lead. Using Avogadro's number: (6.0221415 * 1023 atoms/mol)(0.39 mol) = 2.349 * 1023 atoms.
the constant Mole (mol): 6.02 x 10^23 are how many atoms you have per mol so the answer can be 7 mol atoms or 6.02 x 10^23 atoms per mol x 7 actual answer is 4.214 X10^24 atoms in 7 mol
A mol = 6,022x10^23 atoms 1,5 mol = 9,033x10^23 atoms Always.
There are 1.204 x 1023 atoms in .200 mol of Pb.
6.755 moles lead (6.022 X 1023/1 mole Pb) =6.755 x 6.022 X 1023 =4.068 X 1024 atoms of lead =====================
There are 1.41 e24 atoms of Na in 2.35 mol of NaCl.
0.45 mol BaSO4 have 2,698.10e23 sulfur atoms.

Assuming you are talking about a period made by carbon atoms (Pencil lead is almost pure carbon) and that period has a mass of 0.0001g Then the answer is 5x1018 atoms.There are 12.011g of carbon per mol, there are 6.022x1023 atoms per mol.1mol | 6.022x1023 atoms | 0.001 g |-----------|--------------------------|-------------| = 5x1018 atoms/period12.011g | 1 mol | period |
The answer is 18,061.1023 atoms.
