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.
The formula mass of aluminum oxide (Al2O3) is approximately 102 atomic mass units.

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.
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.
Atomic mass of sodium is 23. The atomic mass of oxygen is 16. Therefore the molecular mass of sodium oxide is 23x2+16=62u.The atomic mass of oxygen is 16. Atomic mass of sodium is 23. Therefore the molecular mass of the given compound is 62 grams per mole.
The molar mass of iron (III) oxide (Fe2O3) is approximately 159.69 g/mol. This is calculated by adding the atomic masses of two iron atoms and three oxygen atoms, which are 55.85 g/mol and 16.00 g/mol respectively.
To calculate the molar mass of sodium oxide (Na2O), you would add the atomic masses of sodium (Na) and oxygen (O) together. The atomic mass of sodium is 22.99 g/mol (from the periodic table) and oxygen is 16.00 g/mol. Therefore, the molar mass of sodium oxide is 2*(22.99) + 16.00 = 61.98 g/mol.
The molar mass of an oxide depends on the specific compound you are referring to, as different oxides have different compositions. To calculate the molar mass of an oxide, you would need to add up the atomic masses of all the elements present in the compound according to their stoichiometric ratios.
The molar mass of calcium oxide is 56.077 grams per mole
The mass of a molecule of copper oxide is the sum of the atomic masses of copper (Cu) and oxygen (O) in the molecule. The molecular formula of copper oxide is CuO, so the mass would be the atomic mass of Cu (63.55 g/mol) plus the atomic mass of O (16.00 g/mol), which equals 79.55 g/mol.
Zinc oxide is a compound so it doesn't have an atomic number.
16 moles of MCO3 is needed to produce 2.8 grams of oxide of M Relative atomic mass - C 12 O 16 M 40.
