The IUPAC name for Fe2O3 is Iron (III) oxide. Rusting is the common name for the corrosion of iron or steel.
Rusting of iron is known as as corrosion and withinside the procedure of corrosion the iron get transformed into iron oxide and that is an instance of chemical change. The chemical formula of rust is Fe2O3. The interplay of Iron with air and water produces rust. The Oxygen exist withinside the air shape a powdered substance known as rust. The rust is a red-orange flaky substance and the phenomenon of the formation of rust is known as rusting. Rusting is an oxidation procedure, and is much more likely to arise at the steel surface.
Therefore, the IUPAC name for Fe2O3 is Iron (III) oxide.

In chemistry we like the number of atoms or molecules in moles.
If one mole is equal to 6.02*10^23 atoms and you have 9.00 *10^23 atoms then how many moles do you have?
Answer;
= 1.495 moles
Explanation;
-One mole contains 6.02 ×10^23 particles
Therefore;
1 mole = 6.02 ×10^23 atoms
Thus; 9.00 ×10^23 atoms will have;
= 9.00 ×10^23 atoms / 6.02 ×10^23 atoms
= 1.495 moles

Explanation:
Before doing any calculations, it's worth noting that atoms do not contain moles, it's the other way around.
A mole is simply a collection of atoms. More specifically, you need to have exactly

In your case, you must determine how many moles of lead would contain

Well, if you know that one mole of lead must contain
