One mole of barium nitrate contains six moles of oxygen atoms. One formula contains 6 atoms.
Water is compound that has 2 hydrogen atoms and 1 oxygen atom: H2O.
9 moles (there are four oxygen atoms for every mol of BaSO4, so you multiply 2.25 by 4)
3,45 grams of H2O contain 1,154.10e23 oxygen atoms.
Olivine is composed of iron, magnesium, and silicate ions and does not contain any oxygen atoms.
Iodide is the I- ion, so it contains no oxygen atoms at all. Perhaps you meant iodate. It has 3 oxygen atoms per iodine atom: (IO3)-.
5,26 moles of oxygen contain 31,676.10e23 atoms.

3 Ni(OH)2 contain six oxygen atoms.

No, simple sugars do not contain as many carbon atoms as oxygen atoms. Simple sugars, like glucose or fructose, have the chemical formula C6H12O6, which means they have 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms.
Barium nitrate has 6 oxygen atoms.
In a molecule of calcium (Ca), there are no atoms of oxygen. Calcium itself does not contain any oxygen atoms in its molecular formula.
There are twice as many oxygen atoms as carbon atoms in carbon dioxide, so 100.0 moles of carbon dioxide would contain 200.0 moles of oxygen atoms.
Not necessarily. Amines contain nitrogen, but many do not contain oxygen.
