1 mole H2O (1 mole O/1 mole H2O)(6.022 X 1023/1 mole O)
6 X 1023 oxygen atoms
=======================to be correct in significant figures and to show you the proper set up for more complex problems
one mole of any element contains a fixed no. of particles 6.022 x 1023
two molecule
O2 is a diatomic molecule.
One mole of barium nitrate contains six moles of oxygen atoms. One formula contains 6 atoms.
2.55 X 1024 oxygen atoms ( 1 mole O /6.022 X 1023)(1 mole N2O3/3 mole O) = 1.41 moles dinitrogen trioxide =======================
1 mole of 02 gas has 12,044 281 714.1023 atoms.
Since each mole of carbon dioxide molecules contains two moles of oxygen atoms, as indicated by the formula CO2 for carbon dioxide, half a mole of carbon dioxide will have one mole of oxygen atoms.

1 mole of oxygen is 6.022 x 1023 atoms. 1 mole of atoms of any element is always 6.022 x 1023 atoms. 1 mole of anything is 6.022 x 1023 of that thing. For example, 1 mole of cars is 6.022 x 1023 cars.
One mole of barium nitrate contains six moles of oxygen atoms. One formula contains 6 atoms.
Zero. The formula for hydrogen chloride gas is HCl. It does not contain oxygen.
2.55 X 1024 oxygen atoms ( 1 mole O /6.022 X 1023)(1 mole N2O3/3 mole O) = 1.41 moles dinitrogen trioxide =======================
1 mole of 02 gas has 12,044 281 714.1023 atoms.

6.0221415 x 10^22 atoms
There are 2 hydrogen atoms and 1 oxygen.
There are 6.022x10^23 atoms in one mole of oxygen, or Avogadro's number.
1 mole of CO2 has 1 mole of carbon atoms and 2 moles of oxygen atoms. So, 0.000831 mole of CO2 will have 0.000831 mole of carbon atoms.
1 mole H2SO4 x 4 moles O/mole H2SO4 x 6.02x10^23 atoms of O/mole O = 2.4x10^34 oxygen atoms
