No, when 100g of iron reacts with oxygen to form iron oxide, the resulting compound will have a different mass than the initial iron due to the addition of oxygen atoms. The mass of the iron oxide formed will be greater than 100g, as the oxygen atoms combine with the iron atoms to form 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
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.

Assuming you are talking about pure sulfer. Atomic weight of Sulfer is : 32.07g/mol 100g / 32.07 g/mol = 3.06 mol (rounded to nearest 2 decimal place) 1 mol = 6.022 141 79 × 1023 atoms. 3.06 X 6.022 141 79 × 1023 = 1.82 X 10^24 atoms
The number of atoms of lead is 6,68.10e23.

There are approximately 6 x 10^22 carbon atoms in 8g of pencil lead.
It really depends. 100 grammes of feather would be a lot bigger than 100 grammes of lead, for example.
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.
