1. The correct chemical formula of barium hydroxide is Ba(OH)2.
2. The molecule of barium hydroxide contain 2 oxygen atoms.
There are two oxygen atoms in one unit of the compound Ba(OH)2.
Barium hydroxide contain two atoms of oxygen in the molecule.
There are two oxygen atoms in one unit of the compound Ba(OH)2.
The compound sodium acetate is C2H3NaO2, so each formula unit has 2 oxygen atoms.
Barium hydroxide (the formula is Ba(OH)2) contain two hydrogen atoms.
There are two oxygen atoms in one unit of the compound Ba(OH)2.
There are two oxygen atoms in one unit of the compound Ba(OH)2.
Ba(OH)2 There are two oxygen atoms in the compound unit of barium hydroxide.
Barium hydroxide contain two atoms of oxygen in the molecule.

Barium hydroxide (the formula is Ba(OH)2) contain two hydrogen atoms.
Ba(OH)2 has 2 oxygen atoms. It is the chemical formula for barium hydroxide.
There is no such compound as BaNO3. The correct formula for barium nitrate is Ba(NO3)2 and in this case, each formula unit would have 6 x 6.02x10^23 atoms of oxygen
Well take Si (as its own element, being silicon) and see how many atoms it has in that one unit, which would be 1 (notice that it has no number next to it) then see how many atoms are in the O2 (Oxygen) obviously it has 2 because of the number next to it. So you take the two numbers and add. 2+1=3. 3 atoms are present.
In the compound 4Fe₃O₂, there are 2 oxygen atoms per formula unit of Fe₃O₂. Since there are 4 formula units (as indicated by the coefficient 4), you multiply 2 oxygen atoms by 4, resulting in a total of 8 oxygen atoms. Therefore, there are 8 oxygen atoms in 4Fe₃O₂.
