In each MOLECULE of Pb3PO4 there would be 3 lead atoms, but Pb3PO4 is not a correct formula. The formula for lead phosphate would be Pb3(PO4)2. There are still 3 lead atoms per molecule of the compound.

There are 6 atoms in dioxide lead because there 1 hydrogen atom and 5 nitrogen atoms
tetra-ethyl lead means lead and ethyl taken four times in ethyl 7 atoms will be present there fore in tetra ethyl 28 atoms will be present.i9n tetra-ethyl lead 1 lead atom will be present so in total 28+1=29 atoms will be present in tetra-ethyl lead.
6.747 moles of lead (6.022 X 10^23/1 mole Pb) = 4.063 X 10^24 atoms of lead
Eight hydrogen atoms are necessary (ethyl methyl ether).
Elements with atomic numbers 1-5 are lighter than carbon.
There are 6 atoms in dioxide lead because there 1 hydrogen atom and 5 nitrogen atoms
The number of atoms of lead is 6,68.10e23.
The number of atoms of lead is 6,68.10e23.

I assume you mean pure Lead, and I'm here to tell you that Lead is an element in the periodic table. The fact that it is an element means that it is only 1 type of atom; Lead! The atomic symbol for Lead is Pb.
6.747 moles of lead (6.022 X 10^23/1 mole Pb) = 4.063 X 10^24 atoms of lead
There are _no_ fluorine atoms. Rather, there are four chlorine atoms.
2.16 X 1024 atoms lead (1 mole Pb/6.022 X 1023) = 3.59 moles of lead ==============
3.25 X 10^20 atoms lead (1 mole lead/6.022 X 10^23) = 5.40 X 10^-4 moles lead
