1 mole of any substance has 6.022 x 1023 atoms or molecules of that substance
0.44 mole Pb (6.022 X 10^23/1 mole Pb) = 2.6 X 10^23 atoms of lead
6.25 X 10^20 atoms of lead (1 mole Pb/6.022 X 10^23)(207.2 grams/1 mole Pb) = 0.215 grams of lead
2.3456 grams lead (1 mole Pb/207.2 grams) = 0.01132 moles of lead =================
mass of one mole of oxygen atom is 16 grams. atomic weight of any atom is equal to mass of 1 mol of that atom...
Approximately 2 / (6.022 x 1023) = 3.32 x 10-24 grams
0.44 mole Pb (6.022 X 10^23/1 mole Pb) = 2.6 X 10^23 atoms of lead
A lot! 9.51 X 103 grams Pb (1 mole Pb/207.2 grams) = 45.9 moles of lead ===============
10 grams lead (1 mole Pb/207.2 grams)(6.022 X 1023/1 mole Pb) = 2.9 X 1022 atoms of lead -----------------------------------
Pb molecular weight is 207.2 g/mol. 33.3 moles of Pb weighs 6899.76 grams.
6.25 X 10^20 atoms of lead (1 mole Pb/6.022 X 10^23)(207.2 grams/1 mole Pb) = 0.215 grams of lead
8.90 X 1023 lead atoms (1 mole Pb/6.022 X 1023)(207.2 grams/1 mole Pb) = 306 grams of lead =============
mole
there are 6.022 x 1023 atoms in 1 mole, so if you have 6.755 moles of Pb that would be be 6.755(6.022 x 1023) which is 4.067861 x 1024 atoms
If the Atomic Mass of an atom is x, then the mass of 1 mole of the atoms is x gram.
291.25 grams of lead (1 mole Pb/207.2 grams)(6.022 X 10^23/1 mole Pb) = 8.4648 X 10^23 atoms of lead I think you meant to say atoms, not molecules, as that is not a molecular formula and looks a lot like the symbol for lead with a possessive mark and s.
1 mole has 6,022 141 29(27)×1023 atoms.
2.3456 grams lead (1 mole Pb/207.2 grams) = 0.01132 moles of lead =================
