There are 2 oxygen atoms in 1 molecule of oxygen.
The chemical formula of barium nitrate is Ba(NO3)2; barium nitrate has six oxygen atoms in the molecule.
A molecule is a combination of atoms. To know how many atoms are in one molecule, you have to find out what atoms are in the molecule.
Carbon Dioxide
There are four hydrogen atoms in an ethanal molecule, CH3CHO.
The chemical formula for maltose is C12H22O11, so there are a total of 12 carbon atoms in a molecule of maltose. A molecule of maltose has 11 oxygen atoms, not 12.
Carbon dioxide.
The chemical formula of barium nitrate is Ba(NO3)2; barium nitrate has six oxygen atoms in the molecule.
Not in it, but bonded to it. In this case, you have carbon monoxide. Add another oxygen molecule and you have carbon dioxide. No, a molecule of Oygen would have the formula O2, and it contains two atoms of Oygen. If Carbon was also present then it would not be a molecule of Oxygen. It would be either Carbon monoxide (CO) or Carbon dioxide (CO2).
