Answer:
If the number of atoms stays the same no matter how they are rearranged, then their total weight stays the same.
In all physical and chemical changes, the total number of atoms remains the same, hence when substances interact with one another, combine or break apart, the total weight of the system remains the same

PbSO4 has 1 atom of Pb, 1 atom of S, and 4 atoms of O. So, in total it has 6 atoms.
The smallest component that makes up a chemical element is an atom. Atoms that are neutral or ionized are the building blocks of all solids, liquids, gases, and plasma. A normal atom is 100 picometers across, which is incredibly small.
Protons, which have a positive charge, make up the majority of it, while neutrons, which have no charge, form the remainder. All regular, naturally occurring atoms have protons, neutrons, and electrons that orbit them because they are heavy particles.
A sample's mass in grams should be divided by the periodic table's amu atomic mass, and the result should be multiplied by 6.02 x 1023, or Avogadro's number, to determine how many atoms are there. So, PbSO4 has 1 atom of Pb, 1 atom of S, and 4 atoms of O. So, in total it has 6 atoms.
