What is the atomic mass for oxide?

It doesn't have an Atomic Mass, it is not an element (pure substance) it is a compound and therefore only has a molar mass.


Why is rust an irreversible change?

because the iron and oxygen have combined on an atomic level creating the compound iron oxide and you would need to manipulate it on the atomic level to separate it.


What is the percent of ferric oxide?

Ferric oxide often refers to iron (III) oxide, which has a chemical formula Fe2O3. The atomic mass of iron (Fe) is 55.85 g/mol, and the atomic mass of oxygen (O) is 16.00 g/mol. Therefore, the molar mass of Fe2O3 is 159.69 g/mol. To calculate the percentage composition of iron (III) oxide, divide the atomic mass of iron by the molar mass of the compound and multiply by 100. So, (2 * 55.85) / 159.69 ≈ 0.698 or 69.8% is the percent of ferric oxide.


What is the relative formula mass of lead oxide?

The relative formula mass of lead oxide (PbO) is calculated by adding the atomic masses of the elements in the formula. The atomic mass of lead (Pb) is 207.2 g/mol, and the atomic mass of oxygen (O) is 16.0 g/mol. Therefore, the relative formula mass of lead oxide is 207.2 + 16.0 = 223.2 g/mol.
